Title: Group Announcement Logic
Abstract:
Public announcement logic is used to reason about the epistemic pre- and post-conditions of actions in the form of public announcements. In the talk I will present Group Announcement Logic (GAL), an extension of public announcement logic with constructs (well known from coalition logic) of the form <G>phi, where G is a group of agents. In GAL, the meaning of <G>phi is that there exists an announcement that the members of G can jointly and truthfully make, and after that announcement is made public phi will be true. After introducing GAL I will discuss how it can be used to express properties such as "there is a sequence of truthful public announcements by agents in G, after which phi is true"; the distinction between "agent i knows *that* phi can be achieved by a public announcement" and "agent i knows *how* phi can be achieved by a public announcement"; and meta-logical properties such as axiomatization, expressivity and the complexity of the model checking problem. The talk is based on joint work with Philippe Balbiani, Hans van Ditmarsch and Pablo Seban.

Asian Workshop on Philosophical Logic
http://www.jaist.ac.jp/rcis/awpl/
"Asian Workshop on Philosophical Logic" will be organized by Research
Center for Integrated
Science (RCIS), Japan Advanced Institute of Science and Technology
(JAIST) and held at the
Ishikawa Hightech Ceter near JAIST from 15th to 17th February, 2012.
Originally, the Workshop
was planned to be held in March of the last year.
Our aim is to promote mutual understandings among researchers on logic
working in Asian
countries, and to establish closer collaborations in future. The scope
of the Workshop will cover:
philosophical logic, non-classical logics, algebraic logic, and
their applications in
computer science and cognitive science
The following is a preliminary list of speakers:
Phan Minh Dung (Asian Institute of Technology, Bangkok)
Shier Ju (Sun Yat-sen University, Guangzhou)
Xin Li (JAIST, Ishikawa)
Fenrong Liu (Tsinghua University, Beijing)
Hu Liu (Sun Yat-sen University, Guangzhou)
Yutaka Miyazaki (Osaka University of Economics and Law, Osaka)
Katsuhiko Sano (JAIST, Ishikawa)
Takahiro Seki (Niigata University, Niigata)
Kaile Su (Griffith University, Queensland)
Wen-fang Wang (National Yang Ming University, Taipei)
Chin-mu Yang (National Taiwan University, Taipei)
Xishun Zhao (Sun Yat-sen University, Guangzhou)
During the Workshop, we will have a special session of discussions on
future collaborations,
in particular on research, education and exchange of researchers in
our region.
The workshop will start from the morning of 15th February and will end
in the afternoon of 17th.
We welcome your participation in both talks and discussions from all
areas and all levels, but ask
to inform us if possible in advance of your participation.

以下の要領でセミナー(3つの発表)を開催します。
日時:2012年1月16日(月)13:20-14:50
2012年1月18日(水)13:20-14:50
2012年1月19日(木)15:10-16:40
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)
講演者:Frank Tall (University of Toronto, Canada)
========================================================================
題目:Classic Lindelöf problems and selection principles (talk 1 and 2)
時間:16日(月)と18日(水)1:20-2:50
アブストラクト:
There are many connections between classical topological problems
concerning Lindelöf spaces and selection principles, such as
(generalizations of) Rothberger, Menger, and Hurewicz properties.
In the first talk, we will discuss these connections.
In the second talk, we will pursue further some of the topics introduced in
the first talk, but it is not necessary to have gone to the first talk in
order
to understand the second.
========================================================================
題目:PFA(S)[S]: a useful model (talk 3)
時間:19日(木)3:10-4:40
アブストラクト:
We introduce a model in which important consequences of PFA hold
but also some combinatorics that follow from V=L. This talk is
quite technical and assumes familiarity with proper forcing with
elementary submodels as side conditions.

Title:
A SECOND LOOK AT PROOF-NETS
Date:
11.00 -, January 12th (Thu)
Place:
Room 478, "Research Bldg. No. 2 (Sougou Kenkyu 2-Goukan)"

Abstract:
In logic, we have a reasonable answer to the question :
"What is a typable object?"
but none so far to the question :
"What is a typed object?"
By a second look at proof-nets, especially the ones involving quantifiers,
we shall propose an answer to the second question.

Title: Static Analysis of Multi-Staged Programs via Unstaging Translation
Abstract:
Static analysis of multi-staged programs is challenging because the
basic assumption of conventional static analysis no longer holds: the
program text itself is no longer a fixed static entity, but rather a
dynamically constructed value. This article presents a
semantic-preserving translation of multi-staged call-by-value programs
into unstaged programs and a static analysis framework based on this
translation. The translation is semantic-preserving in that every
small-step reduction of a multi-staged program is simulated by the
evaluation of its unstaged version. Thanks to this translation we can
analyze multi-staged programs with existing static analysis techniques
that have been developed for conventional unstaged programs: we first
apply the unstaging translation, then we apply conventional static
analysis to the unstaged version, and finally we cast the analysis
results back in terms of the original staged program. Our translation
handles staging constructs that have been evolved to be useful in
practice (typified in Lisp's quasi-quotation): open code as values,
unrestricted operations on references and intentional
variable-capturing substitutions. This article omits references for
which we refer the reader to our companion technical report. This is
a joint work with Wontae Choi, Baris Aktemur, and Makoto Tatsuta.
