This workshop focuses on the issues of information spread in a social network of natural and artificial agents as studied by the emerging interdisciplinary field of multi-agent systems, reasoning and social network analysis.

COVID-19 note: the workshop will follow ECAI. If they go virtual, we go virtual (editor's note: they do).

This is one of the main events of the Tbilisi Autumn of Logic, a series of conferences and summer schools taking place in Tbilisi promoting research in pure and applied logic at an international level.

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.

The conference will be preceded by the Sixteenth International Tbilisi Summer School in Logic and Language devoted to courses on core topics of LATD 2020.

We regret to announce that due to the coronavirus pandemic LATD has been postponed to September 2021.

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

The topics of interest include foundational work on various models and approaches for describing computability and complexity over the real numbers. They also include complexity-theoretic investigations, both foundational and with respect to concrete problems, and new implementations of exact real arithmetic, as well as further developments of already existing software packages. We hope to gain new insights into computability-theoretic aspects of various computational questions from physics and from other fields involving computations over the real numbers.

Due to the ongoing COVID-19 pandemia CCA 2020 cannot take place in Bologna, as originally intended. The entire conference will take place virtually on the Zoom online conference platform.

The international Conference "ULTRAMATH 2020" aims to present recent results in the whole spectrum of mathematics which are grounded on the use of ultrafilters and ultraproducts. Its main goals:
- Disseminate information about the various techniques related to the use of ultrafilters and ultraproducts, and their potential to attack open problems.
 - Bring together researchers with different backgrounds, and encourage their collaborations and interactions, especially on topics connecting different areas of mathematics.

Given the current situation and prospects regarding the COVID-19 pandemic disease, the organizers regret to inform that we decided to postpone the UltraMath 2020 Conference to next year.

The conference brings together researchers working on the mathematical foundations of quantum physics, quantum computing, and related areas, with a focus on structural perspectives and the use of logical tools, category-theoretic structures, formal languages, semantic methods, and other computer science techniques applied to the study of physical behaviour in general. Work that applies structures and methods inspired by quantum theory to other fields (including computer science) is also welcome.

QPL 2020 will be co-located with the 36th Conference on the Mathematical Foundations of Programming Semantics (MFPS 2020).

NMR is the premier forum for results in the area of nonmonotonic reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KRR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications.

As in previous editions, NMR 2020 aims to foster connections between the different subareas of nonmonotonic reasoning and provide a forum for emerging topics. Workshop activities will include invited talks and presentations of technical papers. NMR 2020 is co-located with the International Conference on Principles of Knowledge Representation and Reasoning (KR 2020) and the 33rd International Workshop on Description Logics (DL 2020). In particular, NMR 2020 will share a joint session with DL 2020.

Due to the latest developments in Greece with the COVID19 pandemic, the hybrid format (physical and virtual participation) that was planned for NMR 2020 in September is likely to be canceled. The new format, and possibly new dates, for NMR2020 will be announced shortly.

Computer Theorem Proving is becoming a paradigm as well as a technological base for a new generation of educational software in science, technology, engineering and mathematics. The workshop was to bring together experts in automated deduction with experts in education in order to further clarify the shape of the new software generation and to discuss existing systems.

The ThEdu'20 workshop was associated to IJCAR, which due to the COVID-19 crisis is now held as a Virtual Conference. It is our feeling that a virtual meeting might not allow us to fully reproduce the usual face-to-face networking opportunities of our event. So, unfortunately, the ThEdu'20 had better be cancelled.

The interest expressed for the workshop was such, that the PC decided to publish proceedings, in spite of cancellation after IJCAR become virtual. Thanks to a decision of the EPTCS editorial board adapting to the specific situation, the proceedings already received the approval to be published by EPTCS.

In (pure) mathematics there has always existed a strong informal sense of "naturality". "Natural" theories, notions, properties, or proofs are prefered over technical, convoluted, or counterintuitive approaches. If formal mathematics is to become part of mainstream mathematics, its formalizations and user experience have to become more "natural". This workshop broadly addresses the issue of naturality in formal mathematics.

This workshop is part of the 13th Conference on Intelligent Computer Mathematics (CICM 2020).

The Institute of Philosophy of the The Czech Academy of Sciences announces 'LOGICA 2020', the 33nd in the series of annual international symposia devoted to logic. Rhe first session begins on the morning of Tuesday, 16 June. The symposium closes at noon on Friday, 19 June.

Invited speakers: Katalin Bimbo, Rosalie Iemhoff, Alena Vencovska and Diderik Batens.

We announce, with a considerable amount of regret, that Logica 2020 is cancelled due to the global COVID-19 pandemic.

Computational complexity theory was born more than 50 years ago when researchers started asking themselves what could be computed efficiently. Classifying problems/functions with respect to the amount of resources (e.g. time and/or space) needed to solve/compute them turned out to be an extremely difficult question. This has led researchers to develop a remarkable variety of approaches, employing different mathematical methods and theories.

The future development of complexity theory will require a subtle understanding of the similarities, differences and limitations of the many current approaches. The goal (and peculiarity) of the Caleidoscope school is to reunite in a single event as many different takes on computational complexity as can reasonably be fit in one week. The school is aimed at graduate students and researchers who already work in some aspects of computational complexity and/or who would like to learn about the various approaches.

We are sorry to announce that, due to the ongoing COVID-19 epidemic, the 2020 edition of the Caleidoscope school is CANCELLED.  We hope we will be able to propose these great lectures in the summer of 2021.

We invite participation in the XXIII International Summer School in Philosophy of Physics to be held in Urbino 15th-18th June 2020. The topic of the school is 'Philosophy of Quantum Computation' and it will feature lectures given by Michael Cuffaro (Munich Center for Mathematical Philosophy) and Roberto Giuntini (University of Cagliari), with afternoon seminars given by David Vitali (University of Macerata), Gustavo Martin Bosyk (University of Cagliari), and Rossella Lupacchini (University of Bologna). The School will host a limited number of students, graduate students and early researchers depending on a successful application.

Due to the current COVID-19 pandemic, it will be impossible to host the XXIII International Summer School in Philosophy of Physics in Urbino. For this reason, we have decided to move the school online and make it free of charge.

Descriptive set theory discusses the relationship between logical complexity and good behaviour of sets, so-called regularity properties (e.g. Lebesgue measurability, perfect set property, etc.). It is well known that these properties are closely connected to forcing (and in some cases, large cardinals). Modern developments in set theory such as forcing, large cardinals and determinacy give powerful techniques to tackle problems in descriptive set theory. In recent years, set theorists have generalised classical results of descriptive set theory to generalised reals.

Speakers: 1. Vera Fischer (Vienna) 2. Yurii Khomskii (Hamburg & Amsterdam) 3. Dominique Lecomte (Paris) 4. Heike Mildenberger (Freiburg) 5. Dorottya Sziraki (Budapest) 6. Wolfgang Wohofsky (Vienna) 7. Jindrich Zapletal (Gainesville FL) 8. Zoltan Vydnyanszky (Vienna)

Due to the Covid-19 pandemic, the HSTW 2020 will be held online as a Zoom webinar with several zoom meetings as substitute for social events, like cofeebreaks/lunch. Further information about the conference format can be found on the conference homepage.

The ABC Networking Day provides you with the opportunity to discover all research treasures that ABC holds, and connect with other ABC researchers. All researchers (PhDs, post-docs, assistant/associate/full professors) are invited to attend and actively participate.

The Networking Event will consist of:
* ABC Pitch talks: Flash talks that are all about getting to know each other, to foster fresh collaborations, and, possibly, to team-up for grant proposals. In small groups you present your research and/or listen to and discuss all the great research ABC has to offer
* Networking session: in an informal atmosphere, the discussions continue in break-out rooms. These are small gatherings focused on a certain topic or just to get to know each other, it’s up to you!

Formal Concept Analysis (FCA) is a mathematically well-founded theory aimed at data analysis and classification. FCA allows one to build a concept lattice and a system of dependencies (implications and association rules) which can be used for many AI needs, e.g. knowledge processing, knowledge discovery, knowledge representation and reasoning, ontology engineering as well as information retrieval, recommendation, social network analysis and text processing. Recent years have been witnessing increased scientific activity around FCA, in particular a strand of work emerged that is aimed at extending the possibilities of plain FCA w.r.t. knowledge processing. While the capabilities of FCA are extended, new possibilities are arising in the framework of FCA.

The 8th FCA4AI workshop, co-located with ECAI 2020, is (as usual) dedicated to discuss such issues, and in particular:
- How can FCA support AI activities in knowledge discovery, knowledge representation and reasoning, machine learning, natural language processing...
- By contrast, how the current developments in AI can be integrated within FCA to help AI researchers to solve complex problems in their domain.

Unification is concerned with the problem of making two terms equal, finding solutions for equations or making formulas equivalent. It is a fundamental process used in a number of fields of computer science, including automated reasoning, term rewriting, logic programming, natural language processing, program analysis, types, etc.  The International Workshop on Unification (UNIF) is a yearly forum for researchers in unification theory and related fields to meet old and new colleagues, to present recent (even unfinished) work, and to discuss new ideas and trends. It is also a good opportunity for young researchers and scientists working in related areas to get an overview of the state of the art in unification theory.

The 34th International Workshop on Unification is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Universit́e Paris 13. UNIF 2020 will be a satellite workshop of The International Joint Conference on Automated Reasoning (IJCAR 2020).

The aim of this Joint Linearity and TLLA workshop is to bring together researchers who are currently working on linear logic and related fields, to foster their interaction and provide a forum for presenting new ideas and work in progress. We also hope to enable newcomers to learn about current activities in this area. New results that make central use of linearity, ranging from foundational work to applications in any field, are welcome. Also welcome are more exploratory presentations, which may examine open questions and raise fundamental concerns about existing theories and practices.

The International Joint Conference on Rules and Reasoning (RuleML+RR) is the leading international joint conference in the field of rule-based reasoning. Stemming from the synergy between the well-known RuleML and RR events, one of the main goals of this conference is to build bridges between academia and industry.

RuleML+RR 2020 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 provides 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 2020 is co-located with DecisionCAMP 2020 and the 16th Reasoning Web Summer School (RW 2020), as part of the Declarative AI 2020 event. The theme of the 2020 edition is: Explainable algorithmic decision-making

CiE 2020 is the 16th 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 CiE conferences serve as an interdisciplinary forum for research in all aspects of computability, foundations of computer science, logic, and theoretical computer science, as well as the interplay of these areas with practical issues in computer science and with other disciplines such as biology, mathematics, philosophy, or physics.

Due to the current medical situation related to the coronavirus COVID-19 outbreak, the Organizing Committee of CiE2020, in agreement with the CiE Steering Committee, has decided to hold the conference virtually, without a physical gathering. The organizers are committed to recreate the usual CiE climate under the new conditions.

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, models of computation, semantics and verification in new challenging areas.

IJCAR is the premier international joint conference on all topics in automated reasoning. It is the merger of leading events in automated reasoning: CADE (Conference on Automated Deduction), FroCoS (Symposium on Frontiers of Combining Systems), ITP (International Conference on Interactive Theorem Proving) and TABLEAUX (Conference on Analytic Tableaux and Related Methods). JCAR 2020 will be co-located with the conference FSCDThe IJCAR 2020 technical program will consist of presentations of high-quality original research papers, short papers describing interesting work in progress, system descriptions, and invited talks.

Woody Bledsoe Travel Awards will be available to support selected students attending the conference.

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 the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressiveness and lucidity of the reasoning process.

LFMTP 2020 is affiliated with FSCD 2020 and IJCAR 2020. To celebrate the 60th birthday of Frank Pfenning and his great many contributions to the topics of LFMTP, one session will be devoted to talks by collaborators and friends of Frank.

Davide Rizza and Matt Parker are editing one of the forthcoming EJPS (European Journal of Philosophy of Science) topical collections, on "Dimensions of Applied Mathematics".

Philosophical interest in the application of mathematics has usually been connected to indispensability arguments or Wigner’s famous puzzle of ‘unreasonable effectiveness’. In both cases the success of mathematical applications has been taken as a  starting point for philosophical reflection and, as a result, little attention has been paid to the practice of applying mathematics in the course of scientific enquiry. This special issue is devoted to exploring the latter, relatively neglected topic. We encourage submissions, especially from non-mainstream areas of philosophy of science and/or from under-represented groups, discussing any of the dimensions (historical, foundational and practical) of applied mathematics.

Note: Deadline has been extended to 30 June.

The aim of GandALF 2020 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-fertilisation.

This year, GANDALF will be organised together with a workshop on Stochastic Games organised by the GAMENET network which will held on September 23-24, 2020. The GAMENET meeting will focus on stochastic games with applications in computer science, economy and mathematics.

Due to COVID19 outbreak, the local organization committee and the steering committee of Gandalf have decided that the conference will be organized online this year.

The aim of this Joint Linearity and TLLA workshop is to bring together researchers who are currently working on linear logic and related fields, to foster their interaction and provide a forum for presenting new ideas and work in progress. We also hope to enable newcomers to learn about current activities in this area. New results that make central use of linearity, ranging from foundational work to applications in any field, are welcome. Also welcome are more exploratory presentations, which may examine open questions and raise fundamental concerns about existing theories and practices.

The International Joint Conference on Rules and Reasoning (RuleML+RR) is the leading international joint conference in the field of rule-based reasoning. Stemming from the synergy between the well-known RuleML and RR events, one of the main goals of this conference is to build bridges between academia and industry.

RuleML+RR 2020 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 provides 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 2020 is co-located with DecisionCAMP 2020 and the 16th Reasoning Web Summer School (RW 2020), as part of the Declarative AI 2020 event. The theme of the 2020 edition is: Explainable algorithmic decision-making

CiE 2020 is the 16th 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 CiE conferences serve as an interdisciplinary forum for research in all aspects of computability, foundations of computer science, logic, and theoretical computer science, as well as the interplay of these areas with practical issues in computer science and with other disciplines such as biology, mathematics, philosophy, or physics.

Due to the current medical situation related to the coronavirus COVID-19 outbreak, the Organizing Committee of CiE2020, in agreement with the CiE Steering Committee, has decided to hold the conference virtually, without a physical gathering. The organizers are committed to recreate the usual CiE climate under the new conditions.

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, models of computation, semantics and verification in new challenging areas.

IJCAR is the premier international joint conference on all topics in automated reasoning. It is the merger of leading events in automated reasoning: CADE (Conference on Automated Deduction), FroCoS (Symposium on Frontiers of Combining Systems), ITP (International Conference on Interactive Theorem Proving) and TABLEAUX (Conference on Analytic Tableaux and Related Methods). JCAR 2020 will be co-located with the conference FSCDThe IJCAR 2020 technical program will consist of presentations of high-quality original research papers, short papers describing interesting work in progress, system descriptions, and invited talks.

Woody Bledsoe Travel Awards will be available to support selected students attending the conference.

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 the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressiveness and lucidity of the reasoning process.

LFMTP 2020 is affiliated with FSCD 2020 and IJCAR 2020. To celebrate the 60th birthday of Frank Pfenning and his great many contributions to the topics of LFMTP, one session will be devoted to talks by collaborators and friends of Frank.

The Women in Logic workshop (WiL) provides an opportunity to increase awareness of the valuable contributions made by women in the area of logic in computer science. Its main purpose is to promote the excellent research done by women, with the ultimate goal of increasing their visibility and representation in the community. Women in Logic 2020 is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Universit́e Paris 13, made of Petri Nets 2020, IJCAR 2020, FSCD 2020, and over 20 satellite events.

Our aim is to:
- provide a platform for female researchers to share their work and achievements;
- increase the feelings of community and belonging, especially among junior faculty, post-docs and students through positive interactions with peers and more established faculty;
- establish new connections and collaborations;
- foster a welcoming culture of mutual support and growth within the logic research community.
We believe these aspects will benefit women working in logic and computer science, particularly early-career researchers.

Thanks to the generous support of SIGLOG, the Vienna Center for Logic and Algorithms (VCLA) and the Institute of Logic, Language and Computation of the University of Amsterdam (ILLC), applications for awards are invited to facilitate students and postdocs, who are authors of accepted papers to register and travel to the WiL 2020. Deadline: May 15, 2020. The awardees of the SIGLOG/VCLA/ILLC Travel Award will be reimbursed for a portion of their travel expenses, and registration costs. There will be at most one award per paper.
