講演会 (上村太一氏)
by Ryoma Shinya 21 Jul '17

21 Jul '17

(重複で受け取られた方はご容赦ください) 皆様，東京大学の新屋です．以下の要領で京都大学の上村太一氏の講演会を実施いたしますので，ふるってご参加ください．新屋良磨東京大学大学院情報理工学系研究科コンピュータ科学専攻 email: ryoma(a)kb.is.s.u-tokyo.ac.jp <mailto:[email protected]> ========== 日時：8/4(金) 午後2時から場所：東京大学理学部化学東館2階化東236教室題目：Homotopy Type Theory 入門 / Fibred Fibration Categories 話者：上村太一 (京都大学数理解析研究所) 第一部 (チュートリアル): Homotopy Type Theory 入門概要: *Homotopy Type Theory* (HoTT) は Martin-Löf 依存型理論の拡張で、ホモトピー論に特化した型理論である。代数トポロジーと計算機科学の橋渡しとなる分野であり、ホモトピー論、高次圏論、数理論理学、定理証明器、依存型プログラミングなどと関わりが深い。特に定理証明器を用いた代数トポロジーおよび数学全般の形式化に使われており、 HoTT による数学の基礎付けと定理証明器上での実装は *Univalent Foundations program* と呼ばれる。本チュートリアルでは、Martin-Löf 依存型理論の基本的な概念と、 HoTT の重要な概念である *univalence axiom* と *higher inductive type* についてインフォーマルに解説する。また、HoTT の圏論的意味論として弱分解系、モデル圏や Shulman の type-theoretic fibration category についても触れる。第二部: Fibred Fibration Categories 概要: We introduce fibred type-theoretic fibration categories which are fibred categories between categorical models of Martin-L\"{o}f type theory. Fibred type-theoretic fibration categories give a categorical description of logical predicates for identity types. As an application, we show a relational parametricity result for homotopy type theory. As a corollary, it follows that every closed term of type of polymorphic endofunctions on a loop space is homotopic to some iterated concatenation of a loop.

Call for papers: Non-classical Modal and Predicate Logics
by Katsuhiko Sano 14 Jul '17

14 Jul '17

皆様、北海道大学の佐野勝彦と申します。2017年12月に広州で開催される国際会議についてご案内申し上げます。どうぞ宜しくお願い致します。佐野勝彦 ------------------------------------------------------------------------------------------------- (* Apologies for any cross-postings. *) Call for papers *** Non-classical Modal and Predicate Logics *** Guangzhou (Canton), China, 4-8 December 2017 http://logic.sysu.edu.cn/wolc2017/ Modalities and predicates have since ancient times been central notions of logic. In the 20th century, various systems of non-classical logics emerged, with applications mainly in Computer Science, but also in many other disciplines such as Linguistics, Mathematics, and Philosophy. Both the theoretical studies and the needs of applications gave rise to the questions of non-classical treatment of quantification and modalities and their accommodation in these non-classical logics. In response, various modal and predicate variants of non-classical logics have been introduced and studied in the past decades. Although there are many good conferences on (mainly propositional) non-classical logics, this conference is one solely dedicated to modal and predicate non-classical logics. The aim of the conference is to bring together researchers in both pure and applied aspects of various branches of non-classical logics, not only to present recent advances in their particular fields, but mainly foster the exchange of ideas between researchers focusing on (1) separate branches of non-classical logic and (2) foundational and applied issues. We invite submissions on both (a) theoretical topics from all branches of mathematical logic (e.g., proof-theory, model theory, game theory, computational complexity, etc.), as well as (b) their applications in various areas (including computer science, linguistics, mathematics, philosophy, etc.). Topics of interest include (but are not limited to): * The study of first- or higher-order variants of non-classical logics, including, but not limited to: - Predicate intuitionistic and superintuitionistic logics - Predicate modal logics (e.g. epistemic, tense, action) - Predicate substructural logics - Predicate many-valued and partial logics - Predicate paraconsistent logics - Predicate conditional logic - Predicate non-monotonic logics * Non-classical theories of quantification over classical logic, such as: - Free logics - Branching quantifiers and IF-logic - Generalized quantifiers * Extensions by modalities of (propositional or predicate) non-classical logics, including: - Modal extensions of (super)intuitionistic, substructural, many-valued, paraconsistent, non-monotonic, etc., logics - Co-algebraic treatment of modalities * Applications of non-classical modal and predicate logics in various areas, including: - Computer science - Linguistics and logical analysis of natural language - Philosophy - Methodology of science - Foundations of mathematics (non-classical mathematics) - Mathematical social sciences (e.g. social choice theory, game theory, decision theory) Strong papers on propositional logics can also be accepted, provided they relate to the themes in the main scope of the conference (e.g., the study of completions in algebraic semantics, propositional quantification, etc.). Full versions of selected papers will be published in a special issue of an international peer-reviewed journal (to be specified). == Invited speakers == Gilles Dowek Xavier Caicedo Thomas Ehrhard Melvin Fitting Rosalie Iemhoff Edwin Mares (more to be announced) == Program committee == Shier Ju (chair) Petr Cintula (chair) Arnon Avron Libor Behounek Rob Goldblatt Minghui Ma Chris Mortensen Hiroakira Ono Alessandra Palmigiano Valentin Shehtman Yde Venema Xuefeng Wen (more to be announced) == Organizing committee == Zhe Lin (chair) == Contacts == Web: http://logic.sysu.edu.cn/wolc2017/ Email: linzhe8(a)mail.sysu.edu.cn == Submissions == Extended abstracts of 1-2 pages (including references) should be submitted via the EasyChair web interface: https://easychair.org/conferences/?conf=ncmpl2017 The typesetting style of the document is free for the moment, but a file written according to LNCS style will be requested upon acceptance == Important dates == Deadline for abstracts: 1 September 2017 Notification of acceptance: 20 September 2017 Conference: 4-8 December 2017 Shier Ju and Petr Cintula Conference chairs

名古屋ロジックセミナー (Arno Pauly氏の講演 7/21)
by Takayuki Kihara 13 Jul '17

13 Jul '17

皆様，名古屋大学の木原貴行です．この度，ブリュッセル自由大学のArno Pauly氏の日本訪問の折に，下記の要領で名古屋ロジックセミナーを開催することとなりました．多数のご参加をお待ちしております．名古屋ロジックセミナー http://www.math.mi.i.nagoya-u.ac.jp/~kihara/logic-seminar.html 日時：7月21日 (金) 15:30〜場所：名古屋大学大学院情報学研究科棟 314室講演者：Arno Pauly (ブリュッセル自由大学) 題目：Computability: From ω^ω to κ^κ アブストラクト： Recently Galeotti and Nobrega [1,2] have suggested to generalize computable analysis and the theory of Weihrauch degrees to higher cardinalities. The central role taken by Baire space ω^ω in the classic theories is then filled by κ^κ for a cardinal κ with κ^{<κ}, the reals are replaced by initial segments of the surreal numbers and Turing machines are generalized to ordinal time Turing machines. Initial investigations have reveiled that some results carry over directly, whereas other core questions can become inpendent of ZFC. I will outline both the classic theory and its the generalization to higher cardinalities. In particular, I will highlight some open questions and challenges.
