名古屋集合論セミナーのご案内:
日時:2012年1月11日(水) 午後2時15分~4時(途中15分休憩)
場所:名古屋大学大学院情報科学研究科棟 322号室
(名古屋市地下鉄名城線名古屋大学駅1番出口より徒歩数分、下記のキャンパスマップのA4にある建物です。)
http://www.nagoya-u.ac.jp/global-info/access-map/higashiyama/
講演者:Franklin D. Tall (トロント大学)
題目:A useful model of set theory
アブストラクト:
I will sketch a method for getting mutually consistent consequences of PFA and V = L.
The talks are unavoidably technical, and assume acquaintance with the method of proper forcing
with elementary submodels as side conditions. The hope is that although listeners are unlikely to
be able to follow all the details presented, they will get enough of the ideas so that they can more
easily study the research papers if they are interested.
多数のご参加をお待ちしております。

Fourth Workshop on
MATHEMATICALLY STRUCTURED FUNCTIONAL PROGRAMMING
25 March, Tallinn, Estonia
A satellite workshop of ETAPS 2012
http://cs.ioc.ee/msfp/msfp2012/
The fourth workshop on Mathematically Structured Functional
Programming is devoted to the derivation of functionality from
structure. It is a celebration of the direct impact of Theoretical
Computer Science on programs as we write them today. Modern
programming languages, and in particular functional languages, support
the direct expression of mathematical structures, equipping
programmers with tools of remarkable power and abstraction. Where
would Haskell be without monads? Functional reactive programming
without arrows? Call-by-push-value without adjunctions? Type theory
without universes? The list goes on. This workshop is a forum for
researchers who seek to reflect mathematical phenomena in data and
control.
The first MSFP workshop was held in Kuressaare, Estonia, in July 2006,
affiliated with MPC 2006 and AMAST 2006. The second MSFP workshop was
held in Reykjavik, Iceland as part of ICALP 2008. The third MSFP
workshop was held in Baltimore, USA, as part of ICFP 2010.
Important Dates:
================
Submission of papers: 23 December 2011
Notification: 25 January 2012
Final versions due: 6 Feburary 2012
Workshop: 25 March 2012
Invited Speakers:
=================
Danko Ilik, Goce Delčev University of Štip, Republic of Macedonia
Neil Ghani, University of Strathclyde, UK
Submission:
===========
Papers must report previously unpublished work and not be submitted
concurrently to another conference with refereed proceedings. Accepted
papers must be presented at the workshop by one of the authors.
There is no specific page limit, but authors should strive for brevity.
Accepted regular papers will be published in the Electronic
Proceedings in Theoretical Computer Science (EPTCS). After the
workshop, there might be an opportunity to publish selected papers in
a journal special issue.
All submissions must be in PDF format and use the EPTCS style
files. Submissions can be made through the EasyChair website, at
http://www.easychair.org/conferences/?conf=msfp2012
ETAPS:
======
European Joint Conferences on Theory and Practice of Software (ETAPS)
is the primary European forum for academic and industrial researchers
working on topics relating to software science. ETAPS, established in
1998, is a confederation of six main annual conferences (one of them,
POST, being new in 2012), accompanied by satellite workshops. ETAPS
2012 is the fifteenth event in the series.
http://www.etaps.org/2012
Host City:
==========
Tallinn, a city of 412,000 people, is the capital and largest city of
Estonia, a small EU member country in Northern Europe, bordering
Russia to the East and Latvia to the south. Located in the north of
the country, on the southern shores of the Gulf of Finland, opposite
Helsinki in Finland, Tallinn is most well known for its picturesque
medieval Old Town, a UNESCO World Heritage site. But it also has a
vivid cultural scene, outperforming most European centres of similar
size. In 2011, Tallinn, along with Turku in Finland, is the Cultural
Capital of Europe.
Tallinn is easy to travel to. Estonia is part of Schengen and the
Eurozone. The Lennart Meri International Airport of Tallinn /TLL) is
only 4km from the city centre.
Programme Committee:
====================

Logic, Algebra and Truth Degrees 2012
http://www.jaist.ac.jp/rcis/latd12/
First Call for Papers
The third official meeting of the EUSFLAT Working Group on Mathematical
Fuzzy Logic [1] will be held on 10-14 September 2012 in Kanazawa, Japan.
The conference is organized by Research Center for Integrated Science [2],
Japan Advanced Institute of Science and Technology [3].
Mathematical Fuzzy Logic is a subdiscipline of Mathematical Logic which
studies the notion of comparative truth. The assumption that 'truth comes
in degrees' has proved to be very useful in many, both theoretical and
applied, areas of Mathematics, Computer Science and Philosophy.
The main goal of this meeting is to foster collaboration between
researchers in the area of Mathematical Fuzzy Logic, and to promote
communication and cooperation with members of neighbouring fields.
The featured topics include, but are not limited to, the following:
. Proof systems for fuzzy logics: Hilbert, Gentzen, natural deduction,
tableaux, resolution, computational complexity, etc.
. Algebraic semantics: residuated lattices, MTL-algebras, BL-algebras,
MV-algebras, Abstract Algebraic Logic, functional representation, etc.
. Game-theory: Giles games, Rényi-Ulam games, evaluation games, etc.
. First-order fuzzy logics: axiomatizations, arithmetical hierarchy,
model theory, etc.
. Higher-order fuzzy logical systems: type theories, Fuzzy Class Theory,
and formal fuzzy mathematics.
. Philosophical issues: connections with vagueness and uncertainty.
. Applied fuzzy logical calculi: foundations of logical programming,
logic-based reasoning about similarity, description logics, etc.
We also welcome contributions on any relevant aspects of related logical
systems (such as substructural and quantum logics, and many-valued logics
in general).

We announce the following talk in Kobe Colloquium on Logic, Statistics and
Informatics:
-------------------------------------------------------------------------
Date and time: Dec. 12, 2011 (Mon.), 15:10 -- 16:40
Place: Presentation Room of "Fuchino Group"
on the 4th Floor of Science and Technology Research Building 3 (Shizenkagakutou Sangokan)
(see: http://www.kobe-u.ac.jp/en/access/rokko/campus.htm)
Speaker: Professor Dr. Peter Vojtas
(Department of Software Engineering of the Charles University in Prague)
Title of the talk: Soundness and completeness of fuzzy Prolog/Datalog.
-------------------------------------------------------------------------
Abstract:
We start with using user preference search as a motivation for
a many valued (fuzzy) model of Prolog/Datalog/Querying. We mention
problems of classical approach with refutation and clausal rules. We
base our semantics on implicative rules and many valued modus ponens. We
prove soundness and completeness of our semantics. We discuss also
clausal approach and fuzzy resolution.
