高等研究所セミナー「可換環論における逆数学」
by 秋吉亮太 28 May '16

28 May '16

早稲田大学高等研究所の秋吉と申します．以下の要領で，高等研究所セミナー「可換環論における逆数学」を開催いたします．ご都合よろしければぜひご参加ください。 ———————————————————————————————————————————————————————————— 次のようなセミナーを予定しております．参加自由です． ------------------------------------------------------------------------------ 高等研究所主催セミナー講演者：佐藤隆（東北大学理学研究科）日時：6月7日（火）16:00—18:00 場所：早稲田大学早稲田キャンパス9号館5階　第2会議室 (URL: http://www.waseda.jp/wias/) タイトル：可換環論における逆数学アブストラクト：　本研究は「逆数学」の手法を用いて，数学史の観点も加味しながら，可換環論をメタ分析する，というものです．可換環論の歴史を大雑把に辿れば，十九世紀中盤の代数的整数論が動機となり，イデアル論を経て，二十世紀前半の抽象代数学の勃興という道筋が見えてきます．この抽象化にあたって，D. Hilbert, Van der Waerden, E. Noetherらの貢献が指摘できます．その一連の抽象化の中で，本質的に必要とされる公理はどのように変わっていったのでしょうか？これまでに得られた結果から，可算な一般の可換環のクラスについて，その理論を展開するには，算術的集合存在公理（体系ACA）が必要かつ十分であることが示唆されます．一方，より狭いアルティン環のクラスの理論については，より弱い公理である弱ケーニッヒの補題（体系WKL）が必要かつ十分であることがC. Conidisにより示されています．それでは，整数環の素イデアル分解，ネータ環の準素イデアル分解，PIDの単因子論など，各クラスの理論を特徴付ける公理はどのようなものになるのでしょうか？本講演では，以上の結果を紹介するとともに，これからの研究を進めるにあたっての困難な点や，解決のアイディアについてお話しします．問い合わせ先：早稲田大学高等研究所　秋吉亮太 (georg.logic(a)aoni.waseda.jp)

IWC 2016 - Call for Papers
by Nao Hirokawa 15 May '16

15 May '16

皆様９月にオーストリアで開催される「合流性に関するワークショップ IWC 2016」の論文募集をご案内致します。今回は TRS Meeting, WST, LC&A との合同開催となっております。関連する話題をお持ちの方は、ぜひ投稿をご検討下さい。廣川 (JAIST) ===================================================================== Call for Papers IWC 2016 5th International Workshop on Confluence Sep 8-9, 2016, Obergurgl, Austria, Part of Computational Logic in the Alps, CLA 2016 http://www.csl.sri.com/~tiwari/iwc2016/ ===================================================================== Confluence provides a general notion of determinism and is widely viewed as one of the central properties of rewriting. Confluence relates to many topics of rewriting (completion, modularity, termination, commutation, etc.) and had been investigated in many formalisms of rewriting such as first-order rewriting, lambda-calculi, higher-order rewriting, constrained rewriting, conditional rewriting, etc. Recently there is a renewed interest in confluence research, resulting in new techniques, tool support, certification as well as new applications. The International Workshop on Confluence (IWC) aims at promoting further research in confluence and related properties. IWC 2016 is part of the Computational Logic in the Alps event to be held in Obergurgl, Austria, during the week Sep 4-10, 2016. Previous editions of the workshop were held in Nagoya (2012), Eindhoven (2013), Vienna (2014), and Berlin (2015). During the workshop, the 5th Confluence Competition (CoCo 2016) takes place. IMPORTANT DATES: * submission June 22, 2016 * notification July 12, 2016 * final version Aug 03, 2016 * workshop Sep 8-9, 2016 TOPICS: Specific topics of interest include: * confluence and related properties (unique normal forms, commutation, ground confluence) * completion * critical pair criteria * decidability issues * complexity issues * system descriptions * certification * applications of confluence INVITED SPEAKERS: * TBD PROGRAM COMMITTEE: * Beniamino Accattoli (INRIA) * Bertram Felgenhauer (University of Innsbruck) * Yves Guiraud (University of Paris 7) * Nao Hirokawa (JAIST) * Koji Nakazawa (Nagoya) * Ashish Tiwari (Menlo Park) SUBMISSION: We solicit short papers or extended abstracts of at most five pages. There will be no formal reviewing. In particular, we welcome short versions of recently published articles and papers submitted elsewhere. The program committee checks relevance and may provide additional feedback. The accepted papers will be made available electronically before the workshop. The page limit for papers is 5 pages in EasyChair style. Short papers or extended abstracts must be submitted electronically through the EasyChair system at: https://www.easychair.org/conferences/?conf=iwc2016

No. 7 Kenta Cho <https://www.google.com/url?q=http://www.cs.ru.nl/K.Cho/&sa=D&ust=1461640002…> (Inst. of Comp. & Info. Sci., Radboud University), Von Neumann algebras from a logical / categorical perspective Many researches at the Nijmegen group involve von Neumann algebras, which are now important not only in quantum physics but also in the context of quantum computation and information. I plan to talk about: 1) basics of von Neumann algebras and quantum theory; 2) von Neumann algebras in effectus theory (a categorical approach to quantum computation and logic); 3) von Neumann algebras as a (categorical, denotational) model of the quantum lambda calculus. -- /_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ Dept. of Computer Science Graduate School of Information Science and Technology The University of Tokyo Akazaki Takumi mail :<ultraredrays(a)gmail.com> mobile : <090-5379-4901> /_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/
