The Novembertagung on the History of Mathematics is an annual international conference aimed at PhD and postdoctoral students (young scholars) in the history of mathematics. In 2018 the Novembertagung will be held in Spain for the first time, at the Institute of Mathematics of the University of Seville (IMUS). The conference will commence on November 28th with a lunch reception; presentations will then begin after lunch and continue throughout the next two days.

The theme of the conference is algorithmic randomness and related topics in computability, complexity and logic such as Kolmogorov complexity and reverse mathematics. This year, the conference has special attention to the connections between these topics and dynamical systems and ergodic theory.

We seem to approach a text that we know to be a work of fiction rather differently than a newspaper article, or a conversation about the weather. An influential view in philosophy is that fictional narratives are prescriptions for the reader to imagine some fictional world, while regular assertions are proposals to update the common ground. But whatever the eventual diagnosis, the (apparent) difference between the interpretation of fiction and of non-fiction already raises interesting linguistic questions: How does a reader even know that a text is fiction? Are there linguistic clues an author may leave that mark a given text as such? And is our formal semantic toolkit, developed for dealing with assertions in every day communication, suitable and sufficient for dealing with the peculiarities of narrative fiction and literary style?

In this workshop we want to bring together linguists and philosophers interested in applying formal semantic tools to linguistic phenomena characteristic of fiction/narrative.

The aim of PCC is to stimulate research in proof theory, computation, and complexity, focusing on issues which combine logical and computational aspects. Topics may include applications of formal inference systems in computer science, as well as new developments in proof theory motivated by computer science demands. Specific areas of interest are (non-exhaustively listed) foundations for specification and programming languages, logical methods in specification and program development including program extraction from proofs, type theory, new developments in structural proof theory, and implicit computational complexity.

PCC 2018 is organized as external event for the trimester on "Types, Sets and Constructions" of the Hausdorff Research Institute for Mathematics.

In the last few decades an impressive amount of foundational research in philosophical logic has been devoted to the development of semantical tools which provide sufficiently fine-grained semantics to deal with important topics of pure and applied modal logic, such as the representation of situations, states of affairs, structured contents, hyperintensional contexts, and agent-related attitudes, like epistemic and prohairetic attitudes. A number of different modal frameworks have emerged to tackle these themes. The aim of this conference is to study the potential of these approaches and to explore new connections between them, by providing a forum to present new ideas and analytical methods.

Invited Speakers: Sergei Artemov (New York), Marta Bilkova (Prague), Hannes Leitgeb (Munich) and Sonja Smets (Amsterdam).

The conference is devoted to non-classical logics: modal, many-valued, temporal, paraconsistent, epistemic, deontic, substructural, and nonmonotonic logic, and their applications in computer science, artificial intelligence, formal linguistics, cognitive studies, as well as the deeper analysis of traditional philosophical problems. We will also celebrate the 25th anniversary of the journal Logic and Logical Philosophy published by the Nicolaus Copernicus University in Toruń and edited by the Department of Logic.

The conference is organized by Departament of Logic and Methodology of Sciences of Lodz University and Department of Logic of Nicolaus Copernicus University.

The first Forcing Project Networking Conference (FPNC2018) is the informal kick-off event of the Forcing Project. The project aims to analyse, from a historical and philosophical point of view, the development of modern set theory since the introduction of the forcing technique. FPNC2018 is devoted to methodological approaches in the study of recent mathematics and focuses on the topics of mathematical philosophy and mathematical practice.

The annual meeting of the Australasian Association of Logic will be held in Wellington. Guest speakers will include Timothy Williamson. The current president of the AAL is Max Cresswell and he will give this year's presidential address. This year's conference will be held in honour of Rob Goldblatt and Max Cresswell. Both Rob and Max will retire from Victoria soon and so this is a chance to celebrate their outstanding contributions to logic.

Traditionally, philosophy of mathematics focused on the formal component of mathematics and ignores the human and social components of the mathematical discipline. In the last decades, some philosophers of mathematics have challenged this traditional view and claimed that many of the features of the discipline of mathematics depend at least partially on interpersonal context and cultural embedding. The special issue entitled "Enabling Mathematical Cultures" aims to cover this broadly interdisciplinary scope, studying the social and cultural features of mathematical research practice and its philosophical ramifications.

Guest editors: Benedikt Loewe, Ursula Martin, Alison Pease.

The 1st workshop of Formal Reasoning and Semantics will be held at the Inter-University Center Dubrovnik (IUC) as a part of the 7th conference Logic and Applications (LAP 2018). The workshop is organized within the research project Formal Reasoning and Semantics (FORMALS).

The emphasis of the project is on applications of logic in computer science, and vice versa, the application of computational tools in logical and mathematical research. Another goal is to apply logic to specific problems of linguistics or, more generally, cognitive and information sciences, as well as interdisciplinary areas in which economics and mathematics overlap (game theory, social choice theory).

Invited speakers: Vivek Nigam.

Poznań Reasoning Week 2018, which is the third edition of PRW, consists of three conferences, aimed at bringing together experts whose research offers a broad range of perspectives on systematic analyses of reasoning processes and their formal modelling:
- Games and Reasoning 2018 (11 september)
- Logic and Cognition 2018 (12-13 september)
- Refutation Symposium 2018 (14-15 september)

The aim of the Games and Reasoning conference is to gather researchers from various fields who use games as tools in their research. The concept of a game includes here serious games, scientific discovery games, gamification techniques in science, games with a purpose as well as the more general approaches using game theoretical framework.

Logic and Cognition is an initiative focusing on research on the interplay of logic, cognitive science, psychology and computer science which aim at shedding the light on actual reasoning processes.

Refutation systems are axiomatic systems applied to non-valid formulas (or sequents). A refutation system consists of refutation axioms and refutation rules. This approach is complementary to standard proof methods.  Although refutation systems are not widely known, we believe that the method has potential and can produce results that are both interesting and useful. The goal of the Refutation Symposium is to explain key concepts and techniques, and present new results on refutation systems.

AixDial will be the 22nd edition of the SemDial workshop series, which aims to bring together researchers working on the semantics and pragmatics of dialogue in fields such as formal semantics and pragmatics, computational linguistics, artificial intelligence, philosophy, psychology, and neuroscience. In 2018 the workshop will be hosted by Aix Marseille University, and organized by the Language and Speech Lab (LPL) as well as the Computer Science Lab (LIS). It will be collocated with the Workshop on Prosody and Meaning: Information Structure and Beyond.

The Asian Workshop on Philosophical Logic (AWPL) is an event-series initiated by a group of Asian logicians, and in 2012 the first installment took place at the JAIST in Japan. It is devoted to promote awareness, understanding, and collaborations among researchers in philosophical logic and related fields. The workshop emphasizes the interplay of philosophical ideas and formal theories. Topics of interest include non-classical logics, philosophical logics, algebraic logics, and their applications in computer science, cognitive science, and social sciences. The second and third workshop took place successfully in Guangzhou (2014) and Taipei (2016), respectively. And the two post conference proceedings were published in the Studia Logica book series "Logic in Asia" (http://www.springer.com/series/13080?detailsPage=titles) with Springer.

The Fourth Asian Workshop on Philosophical Logic (AWPL 2018) will be held in Beijing, China, on 20-21 October 2018, organized by the Tsinghua-UvA Joint Research Centre for Logic at Tsinghua University.

Logical and semantic frameworks are formal languages used to represent logics, languages and systems. These frameworks provide foundations for the formal specification of systems and programming languages, supporting tool development and reasoning.

Invited Speakers: Yiannis Moschovakis (Los Angeles & Athens), Andreas Herzig (CNRS, IRIT, Toulouse), Alessandra Palmigiano (TU Delft) and Amy Felty (Ottawa).

Accessible categories are notable for their importance in other areas of mathematics, be it through combinatorial model categories in homotopy theory or abstract elementary classes in model theory, with large cardinal axioms from set theory often thrown into the mix. The goal of this workshop is to bring together practitioners from these different fields to try to break down barriers and build new connections.

The aim of GandALF 2018 is to bring together researchers from academia and industry which are actively working in the fields of Games, Automata, Logics, and Formal Verification. The idea is to cover an ample spectrum of themes, ranging from theory to applications, and stimulate cross-fertilization.

Scalarity is a rich field of study in linguistics and logic. Linguistically, it enters into the meaning of a wide range of expressions. The best-known case in degree semantics may well be the gradable adjective (tall, short, likely, good ), but crosscategorially many other cases have been detected and analysed in similar scalar terms. LNAT4 seeks to consider (i) the nature and variation of scalarity in language and logic, (ii) the diagrams proposed for scalar notions, as well as (iii) the nature of possible connections between logico-linguistic scalar concepts and perception scales.

Invited Speakers: Christopher Kennedy (University of Chicago) and Stefanie Solt (Leibniz-Zentrum Allgemeine Sprachwissenschaft (ZAS).

The European Summer School in Logic, Language and Information (ESSLLI) is an annual event under the auspices of the Association for Logic, Language and Information (FoLLI) and brings together logicians, linguists, computer scientists, and philosophers to study language, logic, and information, and their interconnections.

The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning both to describe human reasoning and to model AI approaches. The aim of this series of workshops is to address recent challenges and to present novel approaches to uncertain reasoning and belief change in their broad senses, and in particular provide a forum for research work linking different paradigms of reasoning. The 2018 workshop will be part of the 41st German Conference on Artificial Intelligence (KI-2018).

MIWAI aims to promote AI research in both theoretical and applied research addressing real-world applications. The main objective of the conference is to present the latest research and results of scientists related to AI topics. The theme for this year's event is "Intelligent World". MIWAI 2018 provides opportunities for the delegates to exchange new ideas and establish future collaborations. This year the conference is organized by Mahasarakham University, with association of Vietnam Academy of Science and Technology and University of Science and Technology of Hanoi, Vietnam.

The DL workshop is the major annual event of the description logic research community. It is the forum at which those interested in description logics, both from academia and industry, meet to discuss ideas, share information and compare experiences. The 31st edition will be collocated with the 16th International Conference on Principles of Knowledge Representation and Reasoning (KR 2018).

Computational approaches play an increasingly important role in historical linguistics and typology. During the last two decades, scholars have made significant advances in automatizing and formalizing specific aspects of the workflow of the classic comparative method. But despite the growing interest in automated approaches to historical linguistics, it is obvious that automatic approaches are still far away from being able to replace human experts, and the majority of approaches still makes broad use of manually annotated datasets. More than two decades after the quantitative turn in historical linguistics, we think it is time to reconsider how computational approaches in historical linguistics can be further improved, and where their current limits can be found.

We invite submissions of papers which address one or several of the following questions:
1. How can we improve the automatic identification of cognates?
2. How can computational methods help to infer deeper genetic relations between the world’s language families?
3. How can big data approaches from computational linguistics help to improve classical approaches to historical linguistics?
4. What are the strengths and shortcomings of phylogenetic methods?
5. How does demography and geography influence the spread of languages through time and space?
6. Are there universal tendencies in the evolution of the world’s languages?
7. How to integrate typological features with lexical features for inferring language phylogenies and predicting typological features for ancestral languages?

CCC is a workshop series bringing together researchers from exact real number computation, computable analysis, effective descriptive set theory, constructive analysis, and related areas. The overall aim is to apply logical methods in these disciplines to provide a sound foundation for obtaining exact and provably correct algorithms for computations with real numbers and related analytical data, which are of increasing importance in safety critical applications and scientific computation.

Invited Speakers: Vasco Brattka (Munich, Germany), Akitoshi Kawamura (Fukuoka, Japan), Jaap van Oosten (Utrecht, Netherlands), and Warwick Tucker (Uppsala, Sweden). Tutorial Speaker: Martin Ziegler (Daejeon, South Korea).

On August 26, 2017, our colleague Carolina Blasio fell victim to a fatal car accident in Campinas, Brazil, only one day after successfully defending her PhD thesis "Sobre Noções de Consequência Generalizadas e Lógicas Plurivalentes" (On generalized notions of consequence and plurivalent logics) at UNICAMP (Brazil). She was a young and promising researcher, besides being the administrator of the Brazilian discussion group on Logic, an active member of the Brazilian LaTeX community, and a diligent feminist campaigner. This special issue of Synthese, on Varieties of Entailment, is dedicated to her memory, and is concerned with topics in logic and philosophy of logic related to her fields of interest.

Epistemic planning is the enrichment of automated planning with epistemic notions such as knowledge and belief. In order to achieve formalisms and systems for epistemic planning that are both expressive and practically efficient, it is necessary to combine state of the art from several such sub-areas of artificial intelligence that have so far been considered mostly in separation. Epistemic planning has applications in game playing, human-robot interaction, social robotics, etc.

For this special issue of AIJ, we invite papers on theory, applications, and implemented systems of epistemic planning.

Current political, social and even scientific debates all hinge upon whether data, inferences and/or belief forming processes are reliable. We are calling for philosophical/methodological contributions which help us through these difficult circumstances.

Given the variety of intertwined problems we are calling for contributions addressing the notion of reliability [broadly construed]. Submissions should be prepared like any other submission to Synthese prepared to under-go double-blind peer-review.

Techniques based on formal logic, such as model checking, satisfiability, static analysis, and automated theorem proving, are finding a broad range of applications in modeling, analysis, verification, and synthesis. This school, the eighth in the series, will focus on the principles and practice of formal techniques, with a strong emphasis on the hands-on use and development of this technology. It primarily targets graduate students and young researchers who are interested in developing and using formal techniques in their research. A prior background in formal methods is helpful but not required. Participants at the school can expect to have a seriously fun time experimenting with the tools and techniques presented in the lectures during laboratory sessions.

CLIB covers a broad spectrum of areas related to natural language processing and computational linguistics focused on but not limited to Bulgarian.

Our invited speakers will be: Dr. Zornitsa Kozareva (Amazon), Dr. Sujith Ravi (Google), and Prof. Ruslan Mitkov (University of Wolverhampton).

The 37th Journees sur les Arithmetiques Faible (Days of Weak Arithmetics) will cover traditional topics of the "Days" such as: Provability in weak arithmetics, Definability in weak arithmetics, Weak arithmetics and model theory, Decidability/undecidability of weak logical theories, and Modeling computations in the frameworks of weak arithmetics.

This interdisciplinary conference will bring together researchers in philosophy, theoretical economics, formal political science, computer science and mathematics who have been independently studying similar questions: namely, opinion formation dynamics, peer interactions and deliberation in social groups, and the implications of these phenomena for the epistemic competency of collective decisions.

This colloquium addresses the design and use of models to represent the beliefs and knowledge of agents as well as changes in the beliefs and knowledge of social communities.

The colloquium unites researchers who use a variety of formal tools to study the process of belief formation, belief revision and knowledge updating in social communities. We focus on multi-agent scenarios centered around topics such as belief merge, social-epistemic influence, group knowledge, and belief-polarisation.

Our approach will be interdisciplinary in nature and brings together insights originating from Logic, Game Theory, Belief Revision Theory, Formal Epistemology, Social Science, Network Theory, Cognitive Science and AI.

Workshop held on the occasion of the two PhD defenses by Malvin Gattinger and Chenwei Shi.

The study of dialogue investigates how natural language is used in interaction between interlocutors and how coordination and successful communication is achieved. However, studies on dialogue have often taken for granted that we align our perceptual representations, an unsustainable assumption when we consider interactions between agents with obviously different perceptual capabilities, such as humans and avators or robots.

Contrarily, studies of perception have focussed on how an agent interacts with and interprets the information from their perceptual environment. In the last decade there has been impressive progress on integrated approaches to language, action, and perception. However, these have a limited integration to the dynamics of dialogue and often fail to take into account the incremental and context sensitive nature of language and the environment.

The aim of this workshop is to initiate a genuine dialogue between these related areas and to examine different approaches from computational, linguistic and psychological perspectives and how these can inform each other. It will feature invited talks by leading researchers in these areas, and high level contributed papers, presented as posters, selected through open competition and rigorous review.

The workshop precedes Julia Ilin's PhD defense (June 15, 12h, Agnietenkapel). We will hear talks by the committee members and other experts from the field. The theme of the workshop is the application of universal algebra and topological dualities in the study of non-classical logics.

UNILOG is a logic event in a broad sense. It gathers people from many horizons (philosophy, mathematics, linguistics, computer science, semiotics, cognitive science ...) and the idea is to promote interaction between all these people.

The previous edition in Istanbul gathered more than 400 logicians from about 50 different countries. For the 6th edition we will follow the same format: - A school of logic of 5 days with 30 tutorials - A congress of 6 days with about 30 sessions/workshops - A contest (the topic will be announced soon) - A secret speaker (speaker whose identity is revealed only at the time of her / its / his speech).

Logic and Probability have a long partnership, having survived together as a legacy from Leibniz, Bernoulli, De Morgan, Boole, Bolzano, Peirce, Keynes, Carnap, Popper and several other contemporary thinkers. According to this tradition, the problem of generalizing logical consequence relations raises questions that transcends both logic and probability, as a consequence of modern logical pluralism. This also leads to a probability pluralism, represented by non-standard theories of probability (i.e., theories of probability based on non-classical logics) that open new avenues and pose new challenges to theory and to applications.

All such tendencies and areas of investigation are naturally generalized to possibility logics, necessity logics and other credal calculi that extend probability, considering that belief can be regarded as generalized probability or as evidence. This workshop intends to contribute to the state-of-the-art of such research topics, emphasizing the connections between all such topics.

We organize a workshop on Classification Questions
in Model Theory at UNILOG 2018. Keynote speaker of Workshop: Professor Bruno Poizat (Lyon).

Model theory is the branch of mathematical logic dealing with the connection between a formal language and its interpretations, or models, i.e., it represents links between syntactic and semantic objects. These objects can be used to classify each others producing structural classifications of theories and their models. Solving classification questions valuable characteristics arise (dimensions, ranks, complexities, spectra etc.) for various classes of structures and their theories.

The interplay between logic and argumentation has a long history, from ancient Aristotle's logic to very recent formal argumentation in AI. This is an interdisciplinary research field, involving researchers from, e.g., logic, philosophy, artificial intelligence, and law. The goal of the CLAR 2018 conference is to highlight recent advances in the two fields of logic and argumentation, respectively, and to promote communication between researchers in logic and argumentation within and outside China.

Diagrams 2018 is the tenth conference in the biennial series that started in 2000. The multidisciplinary nature of Diagrams means it encompasses: architecture, art, artificial intelligence, biology, cartography, cognitive science, computer science, education, graphic design, history of science, human-computer interaction, linguistics, logic, mathematics, philosophy, psychology, and software modelling. The conference attracts a large number of researchers from these interrelated fields, positioning Diagrams as the major international event in the area.

LOGICA 2018 is the 32nd in the series of annual international symposia devoted to logic to be held at Hejnice (in northern Bohemia, about 2.5 hours from Prague), on 18 – 22 June 2018.

Invited speakers are Samson Abramsky, Francesco Berto, Danielle Macbeth, and Jaroslav Peregrin. A tutorial will be given by Carles Noguera i Clofent.

The conference, held in honor of Thomas C. Hales on the occasion of his 60th birthday, will feature talks on representation theory, discrete geometry, and formal verification, with 1.5 days dedicated to each of these topics and with broadly accessible public lectures at the interfaces.

As was the case with the earlier editions, EASSS-2018 will offer a rich programme of both introductory and advanced courses on a broad range of topics in the area of Autonomous Agents and Multi-Agent Systems. The courses will be taught by leading researchers in the field and are aimed at Masters and PhD students, but can be attended by any interested researcher.

EASSS 2018 is organised under the auspices of EURAMAS, the European Association for Multi-Agent Systems.

Typically, logical correctness is taken to concern whether or not an argument or proof follows a logical path from premises to conclusions. In recent years, however, such a view has been complicated by the proliferation of logics, approaches to logic, and uses of logic. In this workshop, we intend to discuss the philosophical and logical consequences of these changes with regard to how, or if, there is any sort of criteria by which a logical structure could be deemed correct, and whether or not those criteria are context-relevant in some specifiable manner.

Keynote speaker: Ole HJORTLAND (University of Bergen, Norway).

We organize a one-day workshop on proof theory at the 6th World Congress on Universal Logic. Keynote speakers are Francesca Poggiolesi (Paris) and Alexander Leitsch (Vienna). Organisers: Peter Schroeder-Heister and Thomas Piecha.

The International Association for Computing and Philosophy promotes philosophical dialogue and interdisciplinary research on all aspects of the computational and informational turn. Coming to these issues from a rich variety of disciplines, IACAP's members have a tradition of helping to shape philosophical and ethical debates about the nature, development, application, and limits of computation, information technologies, and artificial intelligence. IACAP's 2018 meeting will gather philosophers, ethicists, logicians, roboticists, computer scientists, and cognitive scientists to explore these topics. Keynote speakers include Ned Block (NYU) and Ed Zalta (Stanford).

You are invited to a one day workshop on the logic of contradictions in Leeds on 22nd June. What follows from a contradiction: everything, something (but not everything), or nothing? What have philosophers and logicians thought historically? What are people saying now?

Speakers: Graham Priest (CUNY), Sara Uckelmann (Durham), Catarina Dutilh Novaes (Groningen) and Alex Douglas (St Andrews). Attendance is free and refreshments will be provided. However, you are asked to register on-line since places will be limited,

The day before the workshop, 21st June, there will be a student workshop introducing current themes in philosophical logic. Graham Priest and Berta Grimau will be speaking at this.

The summer school is aimed at graduate students and advanced undergraduates in the fields of Linguistics, Computer Science, Cognitive Science, Logic, Philosophy, and other related areas. NASSLLI brings these disciplines together with the goal of producing excellence in the study of how minds and machines represent, communicate, manipulate and reason with information. NASSLLI provides a venue where students and researchers from one discipline can learn approaches, frameworks and tools from related disciplines to apply to their own work. Courses offered at NASSLLI range from intensive, graduate level introductory courses to inter-disciplinary workshops featuring prominent researchers presenting their work in progress.

NASSLLI 2018 will consist of a series of courses and workshops, most running daily from Monday June 25 - Friday June 29. In addition, there will be intensive training in a small set of foundational topics the weekend prior to the start of courses (Saturday June 23 - Sunday June 24). Students will have the opportunity to present work at student sessions throughout the event; the call for student submissions will be circulated in early 2018.

The presently announced workshop aims at an account of logic as construed from logicians' practices of writing and reading, both when working a problem in logic. and when communicating logical problems and solutions with othres. Further interests are activities of commenting or reviewing, and of publishing and collecting. In order to take an interdisciplinary stance, the workshop will allow for a variety of approaches.

Keynote speakers: Prof. Dr. Volker Peckhaus (University of Paderborn), Editor-in-Chief of History and Philosophy of Logic Prof. Dr. Dirk Schlimm (McGill University Montreal / LMU Munich) PD. Dr. Matthias Wille (University of Paderborn).

Keynote Speaker: Thomas Noll (Barcelona, Spain)

Description: This workshop shall represent a privileged platform to make an important step forward to new universal approaches to logic(s) of music. The Workshop focuses on the relatively autonomous approaches to logic(s) of music and musical logic, i.e. logic in pieces of musical compositions. We invite composers, conductors, musicians and musicologists interested in the interplay between logic and music to submit a paper or just active participation. Another objective is to bring together researchers from all over the world into closer contact.

The event "Toposes in Como", which represents the second edition of the conference "Topos à l'IHES" held in France in 2015, will consist of a three-day school, offering introductory courses for the benefit of students and mathematicians who are not already familiar with topos theory, followed by a three-day conference featuring both invited and contributed presentations on new theoretical advances in the subject as well as applications of toposes in different fields such as algebra, topology, number theory, algebraic geometry, logic, homotopy theory, functional analysis and computer science.

The Workshop on Logical Geometry and its Applications (WoLGA) at UNILOG 2018 aims to deepen our theoretical understanding of the logical and diagrammatic behavior of Aristotelian diagrams, as well as to broaden our perspective on their (historical and contemporary) applications.

The keynote speaker at WoLGA will be Amirouche Moktefi (Talinn University of Technology, Estonia).

The XXIInd European Symposium on Medieval Logic and Semantics will have the topic "Language, Thought, and Reality: The Continental and British Traditions of Medieval Logic Revisited".

The EPICENTER, our research center on Epistemic Game Theory at Maastricht University, offers this two-week intensive course as an introduction to the blooming field of Epistemic Game Theory. This field takes a new, fresh approach to game theory, and studies how people reason in game theoretic situations before they eventually make a choice. More precisely, it explores how we reason about the minds of others before we make a choice. Hence, the reasoning of people like you and me is at the center stage of epistemic game theory.

The aims of the Young Set Theory workshops are to bring together young researchers in the domain of set theory and give them the opportunity to learn from each other and from experts in a friendly environment. A long-term objective of this series of workshops is to create and maintain a network of young set theorists and senior researchers, so as to establish working contacts and help disseminate knowledge in the field.

Tutorials: Ilijas Farah (York University), Assaf Rinot (Bar-Ilan University), Christian Rosendal (University of Illinois at Chicago) and Dima Sinapova (University of Illinois at Chicago).

Computational social choice is a rapidly growing discipline at the interface of social choice theory and computer science. It is concerned with the application of computational techniques to the study of social choice mechanisms, and with the integration of social choice paradigms into computing.

P&C 2018 is an interdisciplinary meeting which aims to bring together researchers from various domains with interests in physics and computation. Research and important issues relating to the interface between physics and the theories of computation, computability and information, including their application to physical systems, will be presented and discussed. The workshop will be held as a satellite workshop of the 17th International Conference on Unconventional Computation and Natural Computation (UCNC 2018) in Fontainebleau, France, which is being held from 25-29 June 2018.

Invited Speakers: Judit X. Madarász, Oron Shagrir

The workshops in the Philosophy of Information bring together various philosophical perspectives on the nature and dynamics of information, and focus in particular on novel philosophical questions that arise in the information society. The central theme for the 9th workshop in the series is information visualisation.

Our aim is to focus on informational artefacts that encode or convey information in order to try and explain why visualisations can play a certain epistemic role and why certain visualisation are more effective than others. A special attention will be given to the study of how scientists rely on visualisations and how visual artefacts are designed in the sciences. On this basis, we wish to explore convergences between the philosophy of information and the philosophy of science as well as between the formal sciences (logic, computing) and the philosophy of information.

This two days DMV Studierendenkolleg is concerned with the topic of undecidability. In several talks and workshops we will be introduced to the topic and receive an overview, also concerning the intersections with other topics in mathematics (here infinite combinatorics). Finally we will catch a glimpse of today's scientific borders in two research talks.

Speakers: Carolin Antos (U Konstanz), Nathan Bowler (U Hamburg), Martin Goldstern (TU Vienna), Pascal Gollin (U Hamburg), Regula Krapf (U Koblenz-Landau), Christian Reiher (U Hamburg) and Daniel T. Soukup (U Vienna).

As organizers of this year’s ABC Day we want to provide you with the opportunity to discover all research treasures that ABC is hiding, and build bridges to connect the involved researchers. This format is radically different form the former ‘Brain Day’, as the majority of the audience were typically students from the ABC Summer School. This time, especially researchers (PhDs, post-docs, assistant/associate/full professors) are invited to attend and actively participate.

The day will consist of four elements:
- ABC Mission Statement
- Department highlights
- Pitch talks
- Drinks and bites

Using logic as the foundation to understand machine learning to obtain the best of both worlds is a major challenge. The Logic & Learning School is an opportunity to learn from, and interact with, the world's experts leading recent progress in understanding the relationships between logic and learning. These experts come from both academia and some of the leading industrial research labs (Amazon Research and DeepMind).

The programme of the Logic & Learning School consists of ten lectures of three hours each, starting with four introductory courses on computational and statistical learning theory, reinforcement learning and Bayesian inference, and six advanced courses on exciting and recent developments relating logic and learning. The lectures target an audience of logicians and computer scientists broadly construed and do not assume any knowledge on machine learning.  The summer school is perfectly aligned for students who want to attend the four-yearly Federated Logic Conference (FLOC) taking place in Oxford after the summer school.

The Max Planck Institute for Mathematics in the Sciences in Leipzig organizes a Summer School on the Foundations of Geometry in Historical Perspective. The School deals with a selection of topics in history of geometry, philosophy of geometry, and the history and the contemporary perspectives on the foundations of geometry. The School is open to PhD students writing a dissertation in any of the related field, as well as to Master Students in their final years who have a strong interest in the discipline, and post-doctoral researchers who have obtained their PhD since no more than five years and whose main field of research are the history and the foundations of geometry.

The six days of the School are dedicated to an intensive series of lectures and discussions on various aspects of the history of the foundations of geometry, given by leading experts in the field:    Andrew Arana (Université Pantheon-Sorbonne), Vincenzo De Risi (CNRS, Paris), Jeremy Gray (Open University, Milton Keynes), Gerhard Heinzmann (Archives Poincaré, Nancy), Jürgen Jost (MPI MiS, Leipzig), and Victor Pambuccian (Arizona State University, Phoenix).

The major trend in modern logic is the move from logic to logics. The need for formal modelling of reasoning in various fields of science (philosophy, linguistics, AI, cognitive, social and management sciences) led to the design of hundreds of bespoke logics. For instance, the focus on multi-agent interaction and social behaviour has led to the introduction of logics specific to contexts involving e.g. dynamic changes, uncertainty, incomplete and inconsistent information, which are at odds with reasoning as is formalized in classical logic. This rapid expansion has generated the need to develop overarching theories capable to provide uniform proofs of fundamental properties--such as soundness, completeness, analiticity, decidability--for each member of vast families of logics, while at the same time accounting in a modular way for the specific features of each.

Algebraic proof theory is a research area in which these general results can be achieved using insights from algebraic logic, universal algebra, duality and representation theory for classes of algebras.

This workshop aims at bring together researchers in algebraic proof theory and its applications, explore promising research directions, and foster collaborations.

The biennial DEON conferences are designed to promote interdisciplinary cooperation amongst scholars interested in linking the formal-logical study of normative concepts, normative language and normative systems with computer science, artificial intelligence, linguistics, philosophy, organization theory and law.

In addition to these general themes, DEON 2018 will encourage a special focus on the topic: 'Deontic reasoning for responsible AI'.

The ILLC Colloquium is a half-yearly festive event (either the New Year's Colloquium, the Midsummernight Colloquium or the Midwinter Colloquium) that brings together the three research groups at the ILLC. Each colloquium consists of three main talks by representatives from the Logic and Language group, the Language and Computation group and the Logic and Computation group, which are occasionally followed by Wild Idea Talks. The colloquium is concluded by a get together of the entire ILLC community.

Formal tools coming from logic and category theory are important in both natural language semantics and in computational semantics. Moreover, work on these tools borrows heavily from all areas of theoretical computer science. In the other direction, applications having to do with natural language has inspired developments on the formal side. The workshop, affiliated with Federated Logic Conference (FLoC) 2018, invites papers on both topics. Invited speaker: Ann Copestake, University of Cambridge.

Developing formal methods to program and reason about infinite data, whether inductive or coinductive, is challenging and subject to numerous recent research efforts. The understanding of the logical and computational principles underlying these notions is reaching a mature stage as illustrated by the numerous advances that have appeared in the recent years. The workshop aims at gathering researchers working on these topics as well as colleagues interested in understanding the recent results and open problems of this line of research.

For outsiders, the workshop will offer tutorial sessions and survey-like invited talks. For specialists of the topic, the workshop will permit to gather people working with syntactical or semantical methods, people focusing on proof systems or programming languages, and foster exchanges and discussions benefiting from their various perspectives. The workshop is affiliated with FSCD 2018, as part of the Federated Logic Conference of 2018 and is funded by French ANR, RAPIDO project.

Proof complexity is the study of the complexity of theorem proving procedures. The central question in proof complexity is: given a theorem F and a proof system P, what is the size of the smallest proof of F in the system P? Moreover, how difficult is it to construct a small proof? Many ingenious techniques have been developed to try to answer these questions, which bare tight relations to intricate theoretical open problems from computational complexity (such as the celebrated P vs. NP problem), mathematical logic (e.g. separating theories of Bounded Arithmetic) as well as to practical problems in SAT/QBF solving.

The workshop will be part of FLoC and will be affiliated with the conferences SAT'18 and LICS'18.

Strategic reasoning is one of the most active research area in multi-agent system domain. The literature in this field is extensive and provides a plethora of logics for modeling strategic ability. Theoretical results are now being used in many exciting domains, including software tools for information system security, robot teams with sophisticated adaptive strategies, and automatic players capable of beating expert human adversary, just to cite a few. All these examples share the challenge of developing novel theories and tools for agent-based reasoning that take into account the likely behavior of adversaries.

The SR international workshop, held within FLOC 2018, aims to bring together researchers working on different aspects of strategic reasoning in computer science, both from a theoretical and a practical point of view.

The morning sessions will be devoted to tutorials on topics closely related to strategic reasoning, namely cooperative game theory (by Edith Elkind) and parity games (by Marcin Jurdziński).

CL&C is focused on the interplay between, on one side, the exploration of the computational content of classical mathematical proofs, and on the other side, the languages and the semantical models proposed in computer science for this task: continuations, game models, denotational models, learning models and so forth. The scientific aim of this workshop is to bring together researchers from both proof theory and computer science and to exchange ideas. This year, CL&C will be held as a satellite workshop of FSCD 2018 (former TLCA + RTA).

Invited Speaker: Alex Simpson.

Logical frameworks and meta-languages form a common substrate for representing, implementing and reasoning about a wide variety of deductive systems of interest in logic and computer science. Their design, implementation and their use in reasoning tasks, ranging from the correctness of software to the properties of formal systems, have been the focus of considerable research over the last two decades. This workshop will bring together designers, implementors and practitioners to discuss various aspects impinging on the structure and utility of logical frameworks, including state-of-the-art techniques, the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressiveness and lucidity of the reasoning process.

Invited Speakers : Delia Kesner (Université Paris Diderot, France), Kuen-Bang Hou, alias Favonia (Institute for Advanced Study, Princeton, USA), and Grigore Rosu (University of Illinois at Urbana-Champaign, USA).

Several new models of computation have emerged in the last years, and many developments of traditional computation models have been proposed with the aim of taking into account the new demands of users of computer systems and the new capabilities of computation engines.

The aim of this workshop is to bring together researchers who are currently developing new computation models or new features for traditional computation models, in order to foster their interaction, to provide a forum for presenting new ideas and work in progress, and to enable newcomers to learn about current activities in this area.

DCM 2018 will take place in Oxford on July 8, as a one-day satellite event of FLoC 2018, associated to LICS'18.

Women are chronically underrepresented in the LICS community; consequently they sometimes feel both conspicuous and isolated, and hence there is a risk that the under-representation is self-perpetuating. The second Women in Logic Workshop (WiL 2018), held as a LICS associated workshop, will provide an opportunity for women in the field to increase awareness of one another and one another's work, to combat the feeling of isolation. It will also provide an environment where women can present to an audience comprised of mostly women, replicating the experience that most men have at most LICS meetings, and lowering the stress of the occasion; we hope that this will be particularly attractive to early-career women.

HOPOS is devoted to promoting serious, scholarly research on the history of the philosophy of science. We construe this subject broadly, to include topics in the history of related disciplines and in all historical periods, studied through diverse methodologies. We aim to promote historical work in a variety of ways, but especially through encouraging exchange among scholars through meetings, publications, and electronic media.

HOPOS 2018 will take place at the University of Groningen in the Netherlands in July 2018. The local organizers include Professor Martin Lenz, Dr Han Thomas Adriaenssen and Dr Andrea Sangiacomo of the History of Philosophy Department. Keynote speakers: Karen Detlefsen (University of Pennsylvania) and Martin Kusch (University of Vienna).

The ITP conference series is concerned with all topics related to interactive theorem proving, ranging from theoretical foundations to implementation aspects and applications in program verification, security, and formalization of mathematics. ITP is the evolution of the TPHOLs conference series to the broad field of interactive theorem proving.

FSCD covers all aspects of formal structures for computation and deduction from theoretical foundations to applications. Building on two communities, RTA (Rewriting Techniques and Applications) and TLCA (Typed Lambda Calculi and Applications), FSCD embraces their core topics and broadens their scope to closely related areas in logics, proof theory and new emerging models of computation such as quantum computing or homotopy type theory. FSCD'18 is part of The Federated Logic Conference, FLoC 2018.

The International Conference on Theory and Applications of Satisfiability Testing (SAT) is the premier annual meeting for researchers focusing on the theory and applications of the propositional satisfiability problem, broadly construed. In addition to plain propositional satisfiability, it also includes Boolean optimization (such as MaxSAT and Pseudo-Boolean (PB) constraints), Quantified Boolean Formulas (QBF), Satisfiability Modulo Theories (SMT), and Constraint Programming (CP) for problems with clear connections to Boolean-level reasoning. SAT 2018 will take place as part of the Federated Logic Conference (FLoC) in Oxford.

The intention of the workshop is to bring together researchers in Ramsey theory, computability theory, and related areas in combinatorics and logic, to share ideas and results, and to begin or continue collaborations. To this end, the workshop will combine talks with free time for discussions and collaboration.

The FMLAMAS 2018 workshop will provide a working meeting and discussion forum for researchers working on various formal methods and logical aspects of multi-agent systems (MAS) from the perspectives of artificial intelligence, computer science, and game theory. It will address a wide range of issues that arise in these contexts, from theoretical foundations to algorithmic methods, implemented tools, and applications.

The goal of the Logic, Uncertainty and Games School is to contribute towards the creation of cross-disciplinary common grounds for research on rational reasoning and (interactive) decision making under uncertainty. To this end the School will feature three eight-hour tutorials delivered by leading experts in the fields of Logic, Uncertainty and Games.

Each tutorial is followed by one (or more) example-class session aimed at developing in greater detail one specific topic (e.g. the full proof of a theorem or a generalisation of a notion which is being used in a particular case).

Finally, graduate students and junior researchers will deliver Work-in-progress sessions. This will provide them a unique opportunity to receive feedback from the School lecturers, while developing strong inter-disciplinary communication skills.

LCC meetings are aimed at the foundational interconnections between logic and computational complexity, as present, for example, in implicit computational complexity; deductive formalisms as they relate to complexity; complexity aspects of finite model theory and databases; complexity-mindful program derivation and verification; computational complexity at higher type; and proof complexity. LCC 2018 will be part of FLoC 2018.

The program will consist of invited lectures by Mikolaj Bojanczyk (University of Warsaw) and Ugo Dal Lago (University of Bologna and INRIA Sophia Antipolis), as well as contributed talks selected by the Program Committee.

The e-Ideas Group at the University of Amsterdam, Netherlands is pleased to announce its first workshop, taking place in dates 13-14th July 2018 in Amsterdam.

The aim of the workshop will be to foster discussion on the development of mathematics and related themes in philosophy in the German speaking context during the 19th century.

Confirmed keynote speakers: Paola Basso (University of Bucharest, Romania), Paola Cantù (Université Aix-Marseille, France), Jeremy Heis (University of California, Irvine, U.S.A.) and James Tappenden (University of Michigan, U.S.A.).

IJCAR is the premier international joint conference on all topics in automated reasoning. The IJCAR technical program will consist of presentations of high-quality original research papers, system descriptions, and invited talks.

IJCAR 2018 takes place as part of FLoC 2018 and is the merger of leading events in automated reasoning: CADE (Conference on Automated Deduction), FroCoS (Symposium on Frontiers of Combining Systems) and TABLEAUX (Conference on Analytic Tableaux and Related Methods).

Everyday human decision making involves various kinds of non-classical reasoning such as reasoning with uncertainty, exceptions, similarity, vagueness, incomplete or contradictory information and many others. These types of reasoning usually show two intertwined aspects, an ampliative aspect (augmenting the underlying reasoning by allowing more conclusions) and a defeasible aspect (curtailing the underlying reasoning by either disregarding or disallowing some conclusions that somehow ought not to be sanctioned). Several efforts have been put into the study and definition of formalisms within which the aforementioned aspects of everyday reasoning could adequately be captured at different levels. But despite the progress that has been achieved, large avenues remain open for exploration.

DARe aims at bringing together researchers and practitioners from core areas of artificial intelligence, cognitive sciences, philosophy and related disciplines to discuss these kinds of problems and relevant results in a multi-disciplinary forum. The goal of the workshop is to present latest research developments, to discuss current directions in the field, and to collect first-hand feedback from the community.

Explainable AI (XAI) systems embody explanation processes that allow users to gain insight into the system's models and decisions, with the intent of improving the user's performance on a related task. This raises several questions, such as: how should explainable models be designed? How should user interfaces communicate decision making? What types of user interactions should be supported? How should explanation quality be measured? These questions are of interest to researchers, practitioners, and end-users, independent of what AI techniques are used. Solutions can draw from several disciplines, including cognitive science, human factors, and psycholinguistics.

This is the 13th in a series of bi-annual conferences on the applications of logical methods to foundational issues in the theory of individual and interactive decision-making. The three-day conference will give opportunity for paper presentations and discussions.

Among the topics of particular relevance are:
- Modal logics for games and protocols
- Foundations of game and decision theory
- Learning and information-processing models
- Bounded rationality approaches to game and decision theory.

There will be introductory courses and advanced seminars on syntax, phonology, sign language, morphology, semantics, syntax-semantics interface, phonology-syntax interface, language evolution, animal communication and historical linguistics.

The ARQNL workshop aims at fostering the development of proof calculi, automated theorem proving systems and model finders for all sorts of quantified non-classical logics. Non-classical logics - such as modal logics, conditional logics, intuitionistic logic, description logics, temporal logics, linear logic, dynamic logic, deontic logics, fuzzy logic, paraconsistent logic, relevance logic - have many applications in AI, Computer Science, Philosophy, Linguistics and Mathematics. Hence, the automation of proof search in these logics is a crucial task. The workshop will provide a forum for researchers to present and discuss recent developments in this area.

PRUV 2018 will take place during FLoC and associated to IJCAR. The aim of PRUV is to bring together people from different communities (such as the Artificial Intelligence and the Semantic Web community, among others), including theorists and practitioners, working on logics for reasoning about preferences, uncertainty, and vagueness. Making researchers aware of and fruitfully discuss the most recent application areas, new challenges and the existing body of work on logics for reasoning about preferences, uncertainty, and vagueness, respectively is the main goal of this meeting.

The workshop will be held in University of Oxford as a part of Federated Logic Conference FLOC-2018 ( http://www.floc2018.org/ ) in affiliation with 30th International Conference on Computer Aided Verification ( http://cavconference.org/2018/ ) The primary purpose of the workshop series on Fun With Formal Methods (FWFM) is to popularize and disseminate the best practice of popularization of Formal Methods.

The Logic Colloquium 2018 is the annual European summer meeting of the Association of Symbolic Logic (ASL) ,  an international organization supporting research and critical studies in logic. Its primary function is to provide an effective forum for the presentation, publication, and discussion of scholarly work in this area of inquiry.

LC 2018 will include tutorials by Katrin Tent (WWU Münster) and Ulrike Sattler (University of Manchester), a Gödel Lecture by Rod Downey (Victoria University of Wellington), and 6 special sessions on the topics of Descriptive set theory and dynamical systems, Model theory, Proof theory and constructivism, Temporal and multivalued logics, Computability theory, and Philosophy of Logic and Mathematics.

WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers.

This workshop will continue in the tradition established last year of bringing together philosophers, decision theorists, and AI researchers in order to promote research at the nexus between decision theory and AI. Our plan for the second installment is to make connections between decision theory and burgeoning research programs that may play a prominent role in the near future of the discipline - e.g., quantum information theory, social network analysis, and causal inference.

Confirmed Speakers Hans Briegel (University of Innsbruck), Tina Eliassi-Rad (Northeastern University), Dominik Janzing  (Max Planck Institute - Tübingen), Teresa Scantamburlo  (University of Bristol) and Wolfgang Spohn  (University of Konstanz).

CiE 2018 is the fourteenth conference organized by CiE (Computability in Europe), a European association of mathematicians, logicians, computer scientists, philosophers, physicists and others interested in new developments in computability and their underlying significance for the real world.

The conference will feature Special Sessions on Approximation and Optimisation, Bioinformatics and Bio-inspired Computing, Computing with Imperfect Information, Continuous Computation, History and Philosophy of Computing, and SAT-Solving. Tutoral Speakers: Pinar Heggernes (Bergen, Norway) and Bakhadyr Khoussainov (Auckland, NZ). Invited Speakers: Kousha Etessami (Edinburgh, UK), Johanna Franklin (Hempstead, US), Mai Gehrke (Paris, France), Alberto Marcone (Udine, Italy), Alexandra Silva (London, UK) and Jeffrey O. Shallit (Waterloo, Canada).

Mathematical abstraction is a general phenomenon, a process by which we generalize from the properties and relations of particular objects to the abstract, mathematical structure that those objects exhibit. It is a process that can be iterated to achieve higher levels of abstraction, and plays an important role in shaping how we think about and understand empirical phenomena. The main objective of this conference is to explore the philosophical significance of mathematical abstraction from different perspectives: metaphysically, epistemologically, historically, and practically. Particular attention will be devoted to the role of abstraction in mathematical practice.

The conference is concerned with the theory of computability and complexity over real-valued data.

Most mathematical models in physics and engineering are based on the real number concept. Thus, a computability theory and a complexity theory over the real numbers and over more general continuous data structures is needed. Scientists working in the area of computation on real-valued data come from different fields, such as theoretical computer science, domain theory, logic, constructive mathematics, computer arithmetic, numerical mathematics and all branches of analysis. The conference provides a unique opportunity for people from such diverse areas to meet, present work in progress and exchange ideas and knowledge.

The conference CCA 2018 is held in Honour of Klaus Weihrauch's 75th Birthday, and is preceded by the conference Computability in Europe (CiE 2018) that takes place in Kiel, in the north of Germany, from July 30 to August 3, 2018.

Workshop 2: Logical Paradoxes (with Hannes Leitgeb)

The European Summer School in Logic, Language and Information (ESSLLI) is an annual event under the auspices of the Association for Logic, Language and Information (FoLLI) and brings together logicians, linguists, computer scientists, and philosophers to study language, logic, and information, and their interconnections. ESSLLIs attract around 500 participants from all over the world.

The Student Session of the 30th European Summer School in Logic, Language and Information (ESSLII 2018) is a forum for PhD and Master students to present their research at the interfaces of logic, language and computation. It features three tracks: Logic & Computation (LoCo), Logic & Language (LoLa), and Language & Computation (LaCo).

The main aim of this ESSLLI 2018 workshop is to get together linguists, philosophers and cognitive scientists from the two leading research traditions of natural language meaning, often referred to them as "formal semantics" and "conceptual semantics". The workshop provides a platform to investigate and discuss the ways of possible bridges between the two semantic perspectives, and to initiate a deeper conversation and collaboration between them. The workshop intends to gather approaches that show the way how the two perspectives can strengthen each other.

The workshop holds 6 high-quality contributed talks, each of 45 minutes including discussions, and invited talks by Gemma Boleda (Universitat Pompeu Fabra) and James Pustejovsky (Brandeis University).

There are various approaches to ambiguity from a wide variety of perspectives. This is due to the fact that ambiguity exists and arises on many different levels of natural language. We want to bring together scholars working on different aspects of ambiguity, in particular to approach the following questions:
1. What is the core of this phenomenon?
2. What is the common ground in approaching the phenomenon?
3. What can be gained by combining different approaches?

Our special focus is thus on bringing together approaches seeing ambiguity as a mere computational problem and approaches seeing it as a linguistic phenomenon with some interest in itself.

After a full decade of being hosted in various universities, BLAST returns to its birthplace. BLAST aims at bringing together researchers and students in the above-mentioned diverse areas and the scientific program will include three tutorials exposing the audience to various aspects of the these areas. There will also be seven invited lectures and contributed talks.

The summer school will bring together researchers from different disciplines with the goal of providing participants with knowledge about concept research outside of their own fields and to initiate interdisciplinary exchanges and research. The subsequent and co-located international workshop provides an excellent opportunity to present and discuss ongoing research on concepts.

Both events will focus on (but not be restricted to) three core questions: How can we formally describe and model concepts? Where do concepts come from, and how are they acquired? How are concepts used in cognitive tasks?

It is our pleasure to announce that the Sociedade Brasileira de Logica (SBL) and the Division for Logic, Methodology and Philosophy of Science and Technology of the International Union for History and Philosophy of Science and Technology (DLMPST/IUHPST) are organizing the Conference on Mathematical Logic, as a satellite conference of the International Congress of Mathematicians 2018 (ICM 2018), held in Rio de Janeiro from 1 to 9 August 2018.

Invited speakers include Matthias Aschenbrenner, Veronica Becher, Valeria de Paiva, Steve Jackson, Ulrich Kohlenbach, Maryanthe Malliaris, Francisco Miraglia, Lou van den Dries and Joris Van Der Hoeven.

FG-2018 is the 23rd conference on Formal Grammar, to be held in conjunction with the European Summer School in Logic, Language and Information which, in 2018, will take place in Sofia, Bulgaria.

FG provides a forum for the presentation of new and original research on formal grammar, mathematical linguistics and the application of formal and mathematical methods to the study of natural language.

Quantifiers are linguistic expressions encoding representations of quantities. Their study has been one of the great success stories in natural language semantics. On the other hand, the study of the mental representation of numerical and other quantitative information has become an active area of research in cognitive science and neuroscience. This workshop provides a venue for continued exploration of the interface between these two domains.

Keynote Speakers: Jakub Dotlačil (Amsterdam), Michael Franke (Tübingen), and Steven Piantadosi (Rochester).

The second summer school for the EU RISE project SYSMICS (Syntax meets Semantics - Methods, Interactions, and Connections in Substructural Logics) will take place 22-26 August 2018 at Hotel Les Sources in Les Diablerets, Switzerland. This school will precede two logic conferences taking place in Bern the following week: Logic, Algebra and Truth Degrees (LATD) 2018 and Advances in Modal Logic (AiML) 2018.

Tutorials will be given each morning by Peter Jipsen (Chapman University), David J. Pym (University College London), and Alexandra Silva (University College London), and in the early evening there will be lectures by Johan van Benthem (University of Amsterdam), Laura Kovács (Vienna University of technology), and Fred Wehrung (University of Caen). Since places for the school are limited, we ask students to register online via the webpage before 30 April 2018.

In classical descriptive set theory, Baire space is the most central topological space for the study of the real numbers, consisting of functions from omega to omega. Moving from omega to an uncountable cardinal kappa, one can consider *generalised Baire spaces*, the sets of functions from kappa to kappa. The study of these spaces has become a very important subject in set theory in the past decade.

In combination with the KNAW Academy Colloquium "Generalised Baire Spaces", the Royal Netherlands Academy of Arts and Sciences is offering a one day Master Class on the topic of Generalised Baire Spaces, with four 2-hour courses taught by Andreas Blass, Jouko Vaananen, Andrew Brooke-Taylor, and Philipp Schlicht. This Master Class, intended for graduate students, will teach the basic material needed to understand the research results discussed during the colloquium on the two following days.

The study of generalised Baire spaces has developed into a research area in its own right with a rich overarching theory, internally motivated open questions (cf. Khomskii, Laguzzi, Loewe, Sharankou 2016) and an active research community, combining methods and techniques from several branches of set theory as well as classical model theory. While many concepts from the classical setting can be transferred to generalised Baire space and some classical results remain true at uncountable cardinals, in general the rich combinatorial nature of uncountable cardinals causes the theory of the corresponding spaces to differ significantly, e.g., notions which are equivalent in the classical setting can lead to different notions in the generalised theory. Phenomena like this shed light on structures and properties otherwise hidden in the classical setting.

This Academy Colloquium is a reunion of the research community after a hiatus of two years. The Colloquium will be preceded by an associated KNAW Master Class for postgraduate students in order to prepare them for the talks at the Colloquium.

Advances in Modal Logic is an initiative aimed at presenting the state of the art in modal logic and its various applications. The initiative consists of a conference series together with volumes based on the conferences. AiML 2018 is the 12th conference in the series, and will be co-located with the sixth edition of the conference "Logic, Algebra and Truth Degrees" (LATD 2018).

Utrecht Topology Feest 2018 is an international conference in honour of prof. Ieke Moerdijk on the occasion of his 60th birthday.

All lectures are in the Cosmos lecture theatre of the Koningsbergergebouw. There is a conference dinner on Thursday evening.

Mathematical Fuzzy Logic is the sub-discipline of Mathematical Logic that is concerned with the notion of comparative truth. The assumption that "truth comes in degrees" has proved to be very useful in many theoretical and applied areas of Mathematics, Computer Science, and Philosophy. The LATD conference series started as an official meeting of the working group on Mathematical Fuzzy Logic and has evolved into a wider meeting in algebraic logic and related areas. Its main goal is to foster collaboration between researchers in these areas, and to promote communication and cooperation with members of neighbouring fields.

Computational linguistics studies natural language in its various manifestations from a computational point of view, both on the theoretical level (modeling grammar modules dealing with natural language form and meaning, and the relation between these two) and on the practical level (developing applications for language and speech technology). Right from the start in the 1950ties, there have been strong links with computer science, logic, and many areas of mathematics - one can think of Chomsky's contributions to the theory of formal languages and automata, or Lambek's logical modeling of natural language syntax. The workshop assesses the place of logic, mathematics, and computer science in present day computational linguistics. It intends to be a forum for presenting new results as well as work in progress.

The workshop focuses mainly on logical approaches to computational processing of natural language, and on the applicability of methods and techniques from the study of artificial languages (programming/logic) in computational linguistics. We invite participation and submissions from other relevant approaches too, especially if they can inspire new work and approaches.

The aim of the summer school is to cover basic and advanced topics in proof theory. The focus of the first edition will be on structural proof theory, ordinal analysis, provability logic, automated theorem proving, and philosophical aspects of proof. The summer school is co-located with a workshop on proof theory in Ghent (6-7 September), which will also cover other areas like reverse mathematics, proof mining, and proof complexity.

The 18th European Women in Mathematics General Meeting  focuses on female mathematicians and their achievements. As part of this event, the Mini-Symposium on Mathematical Logic concentrates on recent results that demonstrate the fruitfulness of working at the interface between different parts of logic -- that is, model theory, set theory, recursion (or computability) theory and proof theory -- or between logic and other areas of mathematics. Our speakers therefore come from different fields of mathematical logic and are interested in cross-connections between their fields and areas of application such as topology, group theory, real geometry and combinatorics. For the general audience we are planning an introductory lecture on recent developments in model theory and its applications to real geometry.

Invited speakers: Laura Fontanella (Université Aix Marseille), Charlotte Kestner (Imperial College, London) Salma Kuhlmann (University of Konstanz), Heike Mildenberger (Albert-Ludwigs University of Freiburg), Diana Carolina Montoya (Kurt Gödel Research Center, Vienna).

The Conference Computer Science Logic (CSL) is the annual conference of the European Association for Computer Science Logic (EACSL). It is an interdisciplinary conference, spanning across both basic and application oriented research in mathematical logic and computer science. CSL 2018 will be the 27th edition in the series. It will be organised by the School of Computer Science of the University of Birmingham.

The Sinn und Bedeutung (SuB) conference has in recent years emerged as one of the biggest venues for formal semantics and pragmatics representing the full breadth of the field, and we aim to maintain this tradition.

Invited speakers: Berit Gehrke, Wolfram Hinzen, Beth Levin and Judith Tonhauser.

ICGI, which has been organized bi-annually since early nineties, is the major forum for presentation and discussion of original research papers on all aspects of grammatical inference. The theme of ICGI 2018 will include theoretical and experimental analysis of various models of grammatical inference and algorithms for induction of different classes of languages and automata. This year we especially encourage submissions related to the domain of bioinformatics, which will be presented at a special joint session with the collocated Polish Bionformatics Society symposium.

The confirmed keynote speakers include: Colin de la Higuera (Nantes), Johannes Söding (Goettingen), and Frits Vaandrager (Nijmegen).

There is general realization that computational models of languages and reasoning can be improved by integration of heterogeneous resources of information, e.g., multidimensional diagrams, images, language, syntax, semantics, quantitative data, memory. While the event targets promotion of integrated computational approaches, we invite contributions from any individual areas related to information, language, memory, reasoning.

Georg Cantor (1845-1918) is considered by many the father of modern set theory, his notion of cardinality bringing to life a proper class of different infinities! This conference aims to gather leading scientists from various areas of present-day set theory to celebrate his work.

The conference focuses on all that is new in artificial intelligence such as natural language processing, speech processing and human-computer communication and interaction. In its field, this conference is a special event attracting about 150 experts from 30 countries from around the world every year. The fact that the conference proceedings are published by Springer-Verlag in its series of Lecture Notes in Artificial Intelligence further attests to the international prestige of the conference.

The conference program will include oral presentations and poster/demonstration sessions with sufficient time for discussions of the issues raised. Papers will be presented in plenary or topic oriented sessions. The TSD 2018 conference will be accompanied by one-day satellite workshops or project meetings with organizational support by the TSD organizing committee.  Keynote speaker: Kenneth Church, IBM Thomas J. Watson Research Center, USA.

The conference will feature recent research in predicativity. It will bring together mathematicians, computer scientists and philosophers of mathematics working in areas related to the legacy of Hermann Weyl, on this centennial anniversary of the publication of Das Kontinuum.

The International Conference on Computational Models of Argument, COMMA, is a regular forum for presentation and exchange of the latest research results concerning theory and applications of computational argumentation.  COMMA 2018 will be part of a series of events of the Warsaw Argumentation Week, WAW 2018 (6-16 Sept 2018), which will include the next edition of the Summer School on Argumentation (SSA 2018), themed COMMA workshops, the 16th ArgDiap conference, and other cognate meetings and events. In addition to the main conference track, there will be thematically-focused workshops, and a session will be organized for the demonstration of innovative working applications and tools.

The Colloquium Logicum is organized every two years by the "Deutsche Vereinigung fuer Mathematische Logik und fuer Grundlagenforschung der Exakten Wissenschaften" (DVMLG). In 2018 the colloquium is jointly organized by the Chair of Philosophy 1 and the Chair for Theoretical Computer Science of the University of Bayreuth, Germany. The conference will cover the whole range of mathematical logic and the foundations of the exact sciences. In addition to all fields of mathematical logic, this includes the philosophy of the exact sciences, logic in philosophy, and logic in computer science and artificial intelligence.

Keynote Speakers: Isolde Adler (Leeds, England), Joerg Brendle (Kobe, Japan), Douglas Cenzer (Gainesville FL, U.S.A.), Laura Fontanella (Marseille, France), Benny Kimelfeld (Haifa, Israel), Yang Liu (Cambridge, England), Sara Negri (Helsinki, Finland) and Charlotte Werndl (Salzburg, Austria). In addition to the keynote talks, there will be a "PhD Colloquium" with invited presentations of excellent recent PhD graduates.

The aim of the international autumn school "Proof and Computation" is to bring together young researchers in the field of Foundations of Mathematics, Computer Science and Philosophy. Scope: Predicative Foundations, Constructive Mathematics and Type Theory, Computation in Higher Types, and Extraction of Programs from Proofs. There will be an opportunity to form ad-hoc groups working on specific projects, but also to discuss in more general terms the vision of constructing correct programs from proofs.

RuleML+RR 2018 aims to bring together rigorous researchers and inventive practitioners, interested in the foundations and applications of rules and reasoning in academia, industry, engineering, business, finance, healthcare and other application areas. It will provide a forum for stimulating cooperation and cross-fertilization between the many different communities focused on the research, development and applications of rule-based systems.

RuleML+RR 2018 will be part of the Luxembourg Logic for AI Summit (LuxLogAI) "Methods and Tools for Responsible AI", bringing together RuleML+RR 2018, DecisionCAMP 2018, the Reasoning Web Summer School (RW 2018), and the Global Conference on Artificial Intelligence (GCAI 2018).

KI traditionally brings together academic and industrial researchers from all areas of AI, providing an ideal place for exchanging news and research results of intelligent system technology. The technical program of KI 2018 comprises paper presentations as well as tutorials, workshops, and a doctoral consortium.

The international conference "Formal Philosophy" will be held from 1st to 2nd October 2018 ( Moscow, Higher School of Economics). Conference topics include philosophical logic, formal epistemology, formal ontology, formal ethics and other branches of formal and mathematical philosophy.

TIME 2018 aims to bring together researchers interested in reasoning about temporal aspects of information in any area of Computer Science. The symposium, currently in its 25th edition, has a wide remit and intends to cater to both theoretical aspects and well-founded applications. One of the key aspects of the symposium is its interdisciplinarity, with attendees from distinct areas such as artificial intelligence, database management, logic and verification, and beyond. The symposium will encompass four tracks on temporal representation and reasoning in (1) Artificial Intelligence, (2) Databases (3) Logic and Verification, and (4) New areas and Applications.

Since 1994, the RAMiCS conference series has been the main venue for research on relation algebras, Kleene algebras and similar algebraic formalisms, and their applications as conceptual and methodological tools in computer science and beyond.

Knowledge Representation and Reasoning (KRR) is an exciting, well-established field of research. In KRR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. This assumption, that much of what an agent deals with is knowledge-based, is common in many modern intelligent systems. In recent years KRR has contributed to new and emerging fields including the semantic web, computational biology, and the development of software agents.

The KR conference series is the leading forum for timely in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge. Workshops and tutorials will precede the KR technical program and will run on 27-29 October 2018.

KR also features a Doctoral Consortium program, a student mentoring program bringing together PhD students and senior researchers from the area of KR. Application deadline: June 24, 2018.

This will be the 6th world congress organized about the square of opposition after very successful previous editions in Montreux 2007, Corsica 2010, Beirut, 2012, Vatican, 2014, Easter Island, 2016. This is an interdisciplinary event gathering logicians, philosophers, mathematicians, semioticians, theologians, cognitive scientists, artists, linguists and computer scientists.

Object and event perception are core features of human cognitive processing. Further, these core human cognitive abilities may be reflected differently in language and in perception. This symposium aims to integrate perspectives from different areas (including psychology, neuroscience, linguistics, computer science, AI, and philosophy).

The conference will include the Robert Blumberg Distinguished Lecture.

The Symposium series is organized by the Tbilisi State University and the Institute for Logic, Language and Computation (ILLC) of the University of Amsterdam in conjunction with the Institute of Linguistics and Information Science of the Heinrich-Heine-University Düsseldorf. There have been ten instalments of this series of biannual Symposia. The preceding meetings took place in the Georgian mountain resort Gudauri (1995), at the capital of Georgia Tbilisi (1997), in the Black see coastal resort Chakvi (1999), in the spa resort Likani situated in the Borjomi Canyon (2001), Tbilisi (2003), Batumi (2005), Tbilisi (2007), Bakuriani (2009), Kutaisi (2011), Gudauri (2013), Tbilisi (2015) and Lagodekhi (2017).
