KEOD special session
by 小野寛晰 31 May '13

31 May '13

皆様以下のメールを代理投稿します。　小野寛晰 ---------------------------------------- Dear Madam/Sir, I would like to announce the KEOD’s Special Session (this year in Vilamoura, Portugal) devoted to formal and non-formal aspects of nonmonotonicity. Strict applying of the definition of nonmonotonic inference shows that many examples for nonmonotonicity of human thinking as well as constructions, traditionally understood as nonmonotonic have nothing common with the negation of well known Tarski’s condition for monotonic operation. A rejection from nonmonotonic interpretation of those examples and constructions opens new perspectives in researches on human thinking. http://www.keod.ic3k.org/non-nonmonotonicity.aspx With kind regards, Piotr Lukowski - Chair of KEOD’s Special Session: “Non-nonmonotonicity” Department of Cognitive Science Institute of Psychology University of Lodz, Poland

Kobe Colloquium on Logic, Statistics and Informatics, May 28 (Daisuke Ikegami)
by Joerg Brendle 23 May '13

23 May '13

Kobe Colloquium on Logic, Statistics and Informatics 以下の要領でコロキウムを開催します。日時：2013年5月28日（火）13:20-14:50 講演者：Daisuke Ikegami (University of California, Berkeley) 場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室） ============================================================ 題目： Inner models from logics アブストラクト： The goal of this research is to construct a model of set theory which is "close to" HOD but easier to analyze. The motivation comes from Woodin's HOD Conjecture, which states that HOD is very "close to" V under the presence of a very strong large cardinal (extendible cardinal). HOD Conjecture is closely related to the problem of constructing a canonical extender model with a supercompact cardinal and it has striking applications to the theory of large cardinals without the Axiom of Choice. To solve HOD Conjecture, one would expect a fine analysis of HOD. The difficulty of the analysis of HOD lies in the fact that HOD is very "non-absolute", e.g., one could force V = HOD with a proper class partial order. Given that HOD is obtained using full second order logic in the same way as Gödel's constructible universe L via first order logic, in this talk, we use Boolean valued higher order logics to construct inner models of set theory which are more "absolute" than HOD and investigate the properties of the models. ============================================================ 交通：阪急六甲駅またはJR六甲道駅から神戸市バス36系統「鶴甲団地」行きに乗車，「神大本部工学部前」停留所下車，徒歩すぐ． http://www.kobe-u.ac.jp/info/access/rokko/rokkodai-dai2.htm 連絡先：ブレンドレヨーグ brendle(a)kurt.scitec.kobe-u.ac.jp

みなさま，東京大学の蓮尾です．来週火曜日の研究室セミナーでは， Leicester 大学の Irek Ulidowski さんをお迎えしてプロセス計算と event structure に関するご研究をお話いただきます．ぜひご参加ください．蓮尾一郎 http://www-mmm.is.s.u-tokyo.ac.jp/ ________________________________ Tue 21 May 2013, 15:30-17:30 Irek Ulidowski (University of Leicester) Modelling of bonding with processes ad events 理学部7号館1階 102教室 Room 102, School of Science Bldg. No. 7 アクセス： https://www-mmm.is.s.u-tokyo.ac.jp/indexj.html （一番下） Access: http://www-mmm.is.s.u-tokyo.ac.jp/ (see bottom) We introduce two forms of modelling of systems that consist of objects that are combined together by the means of bonds. In reaction systems for bonding we define how bonds are created and dissolved via reduction-style semantics. The usefulness of reaction systems is illustrated with examples taken from software engineering and biochemistry. We also introduce reversible event structures and define the notion of configuration. We then discuss how to give semantics of reaction systems for bonding in terms of reversible event structures.

Monographs by Downey and Hirschfeldt, and by Nies account for the recent research activities in the area. In spite of much work, research on randomness of infinite strings has excluded the investigation of algorithmic randomness for infinite algebraic structures such graphs, trees, groups or more generally universal algebras. In this talk, we provide a framework for reasoning about algorithmic randomness for various classes of infinite structures.

by Nao Hirokawa 10 May '13

10 May '13

皆様 CONCUR 2013 に併設されます、計算モデルに関するワークショップ DCM 2013 の論文募集の案内をお送り致します。ご投稿・ご参加を検討して頂ければ幸いです。廣川　直（JAIST） ====================================================================== Call for Papers DCM 2013 Developments in Computational Models http://www.dcm-workshop.org.uk/2013 Buenos Aires, Argentina Monday August 26 2013 A satellite event of CONCUR 2013 ====================================================================== Several new models of computation have emerged in the last years, and many developments of traditional computational models have been proposed with the aim of taking into account the new demands of computer systems users and the new capabilities of computation engines. A new computational model, or a new feature in a traditional one, usually is reflected in a new family of programming languages, and new paradigms of software development. The aim of this workshop is to bring together researchers who are currently developing new computational models or new features for traditional computational 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 2013 will be a one-day satellite event of CONCUR 2013. Topics of interest include all abstract models of computation and their applications to the development of programming languages and systems: - quantum computation, including implementations and formal methods in quantum protocols; - probabilistic computation and verification in modelling situations; - chemical, biological and bio-inspired computation, including spatial models, self-assembly, growth models; - general concurrent models including the treatment of mobility; - infinitary models of computation; - trust, and security; information-theoretic ideas in computing. SUBMISSION ---------- Submit your paper in PDF format via the conference EasyChair submission page: http://www.easychair.org/conferences/?conf=dcm2013 Submissions should be an abstract of at most 5 pages, written in English. Simultaneous submission to journals, conferences or other workshops is not permitted. Please use the EPTCS macro package and follow the instructions of EPTCS: http://eptcs.org/ http://style.eptcs.org/ A submission may contain an appendix, but reading the appendix should not be necessary to assess its merits.
