In his recent book 'Thin Objects: An Abstractionist Account' (Oxford University Press, 2018), Øystein Linnebo claims that mathematical objects are thin in the sense that "very little is required for their existence". Linnebo articulates this view in terms of Fregean abstraction principles, arguing that it is sufficient for abstract objects to exist that some nonabstract objects, or pluralities thereof, stands in the appropriate equivalence relations. Linnebo set up, among others, a defence of predicative vis-á-vis impredicative abstraction, and articulates a 'dynamic' approach to abstraction itself, on which abstraction is taken to extend the domain of objects available for quantification, and predicative abstraction is iterated over larger and larger domains.

The goal of this Special Issue is to bring together contributions addressing both the philosophical and the technical aspects of Linnebo's book, also in connection to similar proposals in the philosophy of mathematics and logic. Contributions to the Special Issue should consist in short papers (4000-6000 words). Øystein Linnebo will contribute a précis of his book, opening the issue, and a 'Reply to Critics', closing the issue.

The Philosophy of Mathematics Association is an affiliated group of the American Philosophical Association and as such is invited to organize sessions in the group program at APA divisional meetings. The PMA has held such a group session at the 2020 Eastern meeting and the 2021 Pacific meeting, and is hoping to make philosophy of mathematics symposia a regular component of APA divisional meetings. Proposals will be vetted by a joint committee of the PMA and the Association for the Philosophy of Mathematical Practice (APMP), and successful proposals will be scheduled for inclusion at the 2022 APA Eastern division meeting (January 4-8, 2022, Montreal).

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.

Logics of dependence and independence are novel extensions of classical logics aiming at characterizing dependence and independence notions in sciences. This field of research has grown rapidly in recent years. The framework of the logics has found applications also in fields like database theory, linguistics, social choice, quantum physics and so on. This workshop will bring together researchers from all these relevant areas and provide a snapshot of the state of the art of logics of dependence and independence.

This workshop is organized as part of the 32nd European Summer School in Logic, Language and Information (ESSLLI 2021): https://www.esslli.eu. The workshop has a 2-day program. The exact dates will be announced soon, see ESSLLI homepage for updates.

The goal of this workshop is to bring together people interested in structured representations of semantic information, especially from a computational perspective. In recent years, there has been a growing body of research which aims to integrate structured entities into formal semantic accounts. Important developments in this direction are the introduction of rich type systems and the use of frame-based representations, among others. The workshop is open to both foundational issues of structured semantic representations and applications to specific linguistic phenomena.

A first edition of the workshop took place in Gothenburg as part of IWCS 2019.

PotsDial will be the 25th 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 2021 the workshop will be hosted by the Department of Linguistics at the University of Potsdam, Germany. (If the pandemic situation allows for it, there will be a local component for those who want to travel to Potsdam, but fully remote participation, including presentation, will be possible. Please see the website for updates closer to the date.)

MFPS conferences are dedicated to the areas of mathematics, logic, and computer science that are related to models of computation in general, and to semantics of programming languages in particular. This is a forum where researchers in mathematics and computer science can meet and exchange ideas. The participation of researchers in neighbouring areas is strongly encouraged.

MFPS 2021 is co-located with the 9th Conference on Algebra and Coalgebra in Computer Science (CALCO 2021). Due to the pandemic situation, the conference will take place online. Should the situation improve and allow some international travel, we will do our best to organize a small component of the meeting in Salzburg for those participants who wish to attend the meeting in person.

The ability to think about non-actual possibilities is crucial for rational decision and action. When deciding what to do in situations of uncertainty or risk, we use our powers of imagination and conception to surveil the ways the world might be for all we know, and ponder the possible consequences of our actions. What is the logic of conceivability? Do thinking and imagining exhibit sufficient structure so to be amenable to precise modeling? Under what conditions does an imaginative episode establish a non-actual scenario as a real possibility? What are the special features of thought, talk and knowledge about mere possibility and conditionality? The aim of this conference is to facilitate the conversation on these questions by bringing together both senior and rising young researchers from around the world.

The Logical Perspectives conference series aims at bringing together distinguished logicians in order to present their perspectives on the future of the field, to discuss related open problems, and to foster new collaborations. The topics include, but are not limited to:
 - logical methods in mathematics;
 - logical methods in philosophy;
 - logical methods in computer science.

BLAST is a conference series focusing on Boolean Algebras, Lattices, Algebraic Logic, Universal Algebra, Set Theory, Set-theoretic Topology, and Point-free Topology. The series circulates between different universities. The central BLAST web page, with links to past meetings, can be found here: http://math.colorado.edu/blast/

This year's installment of BLAST will take place at New Mexico State University. The scientific program will include invited lectures, tutorial lectures, two special sessions, and contributed talks. Due to the current pandemic, the conference will be entirely online.

The 4th workshop Formal Reasoning and Semantics will be held at the Inter-University Center Dubrovnik (IUC), as a part of the 10th conference Logic and Applications (LAP 2021) 20-24 September 2021. Virtual participation is also possible.

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).

The field of natural language semantics has undergone what some refer to as an 'experimental turn' and is arguably currently undergoing a 'computational turn'. By expanding the toolbox available to the semanticist, these two turns have the effect of expanding the phenomena that can be explained and the varieties of semantic explanations that can be offered.

Given this wider toolbox and purview, we aim to gather a workshop to showcase exciting new work that develops new semantic explanations using experimental and computational methods, as well as to invite broader reflection on the methodology of semantics now and in its future.

From 14-24 June 2021 an impressive cast of international lecturers, from a wide range of disciplines, will try to unravel our capacity for music. Students will, next to attending lectures, work groups and online social events, work in groups with a designated tutor on a research project, within the broad topic of musicality, which they will present towards the end of the Summer School. Organized by Prof. Henkjan Honing and the Music Cognition Group.

After the successful completion of NALOMA'20 (NAtural LOgic Meets MAchine Learning), NALOMA'21 seeks to continue the series and attract exciting contributions.  NALOMA'21 is set out to address two main issues of the NLI community. First, the approaches and systems currently used to address NLI are too one-dimensional: they are either purely DL or purely symbolic but do not attempt to combine the two worlds. A second issue concerns datasets: existing NLI datasets are either complex enough but too small to be used for proper learning, or large enough but too easy to be claimed to represent human inference. The workshop aims to bridge the gap between ML/DL and symbolic/logic-based approaches to NLI, and it is perhaps the only workshop organized to do so. It will take place from June 14-June 18, 2021, during the International Conference on Computational Semantics (IWCS 2021) organized by the University of Groningen but taking place fully online due to the pandemic.

The demand for more sophisticated natural human-computer and human-robot interactions is rapidly increasing as users become more accustomed to conversation-like interactions with AI and NLP systems. Such interactions require not only the robust recognition and generation of expressions through multiple modalities (language, gesture, vision, action, etc.), but also the encoding of situated meaning.

This workshop intends to bring together researchers who aim to capture elements of multimodal interaction such as language, gesture, gaze, and facial expression with formal semantic representations. We provide a space for both theoretical and practical discussion of how linguistic co-modalities support, inform, and align with 'meaning' found in the linguistic signal alone. MMSR 2021 is co-located with IWCS 2021.

Semantic Spaces at the Intersection of NLP, Physics, and Cognitive Science (SemSpace2021) is the latest edition of a series of workshops that brings together research at the intersection of NLP, Physics, and Cognitive Science. Using the common ground of vector spaces, the workshop offers researchers in these areas an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between the three disciplines will foster theoretically motivated approaches to understanding how meanings of words interact with each other in sentences and discourse via grammatical types, how they are determined by input from the world, and how word and sentence meanings interact logically.

This year we are excited to be (virtually) co-located with IWCS.

The TYPES meetings are a forum to present new and on-going work in all aspects of type theory and its applications, especially in formalised and computer assisted reasoning and computer programming.

This year's TYPES will be held virtually (online), possibly in combination with a physical meeting in Leiden in the Netherlands if the political situation permits that. TYPES 2021 will not only consist of presentations, but also a setup of working groups that get together throughout the week. The hope is that we can retain at least some of the exchange and chatter that is the heart of the TYPES conference series.

Under the auspices of the Association for Logic, Language, and Information (FoLLI), the European Summer School in Logic, Language, and Information (ESSLLI) runs every year. Except for 2021, where the school will be virtual, it runs in a different European country each year. It takes place over two weeks in the summer, hosts approximately 50 different courses at both introductory and advanced levels, and attracts around 400 participants from all over the world.

The main focus of ESSLLI is the interface between linguistics, logic and computation, with special emphasis in human linguistic and cognitive ability. Courses, both introductory and advanced, cover a wide variety of topics within the combined areas of interest: Logic and Computation, Computation and Language, and Language and Logic. Workshops are also organized, providing opportunities for in-depth discussion of issues at the forefront of research, as well as a series of invited evening lectures.

Registration is now open. Early registration is available until the 5th of June 2022.

It will take place from June 14-June 18, 2021, during the International Conference on Computational Semantics (IWCS 2021) organized by the University of Groningen but taking place fully online due to the pandemic.

The demand for more sophisticated natural human-computer and human-robot interactions is rapidly increasing as users become more accustomed to conversation-like interactions with AI and NLP systems. Such interactions require not only the robust recognition and generation of expressions through multiple modalities (language, gesture, vision, action, etc.), but also the encoding of situated meaning.

This workshop intends to bring together researchers who aim to capture elements of multimodal interaction such as language, gesture, gaze, and facial expression with formal semantic representations. We provide a space for both theoretical and practical discussion of how linguistic co-modalities support, inform, and align with 'meaning' found in the linguistic signal alone. MMSR 2021 is co-located with IWCS 2021.

Semantic Spaces at the Intersection of NLP, Physics, and Cognitive Science (SemSpace2021) is the latest edition of a series of workshops that brings together research at the intersection of NLP, Physics, and Cognitive Science. Using the common ground of vector spaces, the workshop offers researchers in these areas an appropriate forum for presenting their uniquely motivated work and ideas. The interplay between the three disciplines will foster theoretically motivated approaches to understanding how meanings of words interact with each other in sentences and discourse via grammatical types, how they are determined by input from the world, and how word and sentence meanings interact logically.

This year we are excited to be (virtually) co-located with IWCS.

The TYPES meetings are a forum to present new and on-going work in all aspects of type theory and its applications, especially in formalised and computer assisted reasoning and computer programming.

This year's TYPES will be held virtually (online), possibly in combination with a physical meeting in Leiden in the Netherlands if the political situation permits that. TYPES 2021 will not only consist of presentations, but also a setup of working groups that get together throughout the week. The hope is that we can retain at least some of the exchange and chatter that is the heart of the TYPES conference series.

The DL workshop is the major annual event of the description logic research community. It is the forum in which those interested in description logics, both from academia and industry, meet to discuss ideas, share information and compare experiences.

The Tsinghua-Uva Joint Research Center in Logic organises a series of on-line lectures to commemorate that Wittgenstein's Tractatus first appeared in 1921.

Organized by Prof. Henkjan Honing and the Music Cognition Group.

After the successful completion of NALOMA'20 (NAtural LOgic Meets MAchine Learning), NALOMA'21 seeks to continue the series and attract exciting contributions.  NALOMA'21 is set out to address two main issues of the NLI community. First, the approaches and systems currently used to address NLI are too one-dimensional: they are either purely DL or purely symbolic but do not attempt to combine the two worlds. A second issue concerns datasets: existing NLI datasets are either complex enough but too small to be used for proper learning, or large enough but too easy to be claimed to represent human inference.

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 2021 is a satellite event of the 36th Annual ACM/IEEE Symposium on Logic in Computer Science (LICS'21) to be held virtually on June 29-July 2, 2021.

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.

Invited speakers: Simona Ronchi Della Rocca, Rineke Verbrugge.

The main aim of this conference series is to celebrate the unifying power and interdisciplinary applications of toposes and encourage further developments in this spirit, by promoting exchanges amongst researchers in different branches of mathematics who use toposes in their work and by introducing a new generation of scholars to the subject.

CSR is an annual international conference held in Russia that is designed to cover a broad range of topics in Theoretical Computer Science.

Topics include, but are not limited to: (i) algorithms and data structures (ii) computational complexity, including hardness of approximation and parameterized complexity (iii) randomness in computing, approximation algorithms, fixed-parameter algorithms (iv) combinatorial optimization, constraint satisfaction, operations research (v) computational geometry (vi) string algorithms (vii) formal languages and automata, including applications to computational linguistics (viii) codes and cryptography (ix) combinatorics in computer science (x) computational biology (xi) applications of logic to computer science, proof complexity (xii) database theory (xiii) distributed computing (xiv) fundamentals of machine learning, including learning theory, grammatical inference and neural computing (xv) computational social choice (xvi) quantum computing and quantum cryptography (xvii) theoretical aspects of big data.

Opening lecture: Tim Roughgarden (Columbia University, USA).

Formal Concept Analysis emerged in the 1980's from attempts to restructure lattice theory in order to promote better communication between lattice theorists and potential users of lattice theory. Since its early years, Formal Concept Analysis has developed into a research field in its own right with a thriving theoretical community and a rapidly expanding range of applications in information and knowledge processing including visualization, data analysis (mining) and knowledge management and discovery.

The ICFCA conference series aims at bringing together researchers and practitioners working on theoretical or applied aspects of Formal Concept Analysis within major related areas such as Mathematics and Computer and Information Sciences and their diverse applications to fields like Software Engineering, Linguistics, Life and Social Sciences, etc.
