BOOK ANNOUNCEMENT
Hybrid Logic and its Proof-Theory
by Torben Braüner
Applied Logic Series, Vol. 37
Springer, 2011
ISBN 978-94-007-0001-7
* This is the first book-length treatment of hybrid logic and its
proof-theory. Hybrid logic is an extension of ordinary modal logic which
allows explicit reference to individual points in a model (where the
points represent times, possible worlds, states in a computer, or
something else). This is useful for many applications, for example when
reasoning about time one often wants to formulate a series of statements
about what happens at specific times.
* There is little consensus about proof-theory for ordinary modal logic.
Many modal-logical proof systems lack important properties and the
relationships between proof systems for different modal logics are often
unclear. In the present book we demonstrate that hybrid-logical
proof-theory remedies these deficiencies by giving a spectrum of
well-behaved proof systems (natural deduction, Gentzen, tableau, and
axiom systems) for a spectrum of different hybrid logics (propositional,
first-order, intensional first-order, and intuitionistic).
* All these proof systems can be motivated independently, but the fact
that the systems can be given in a uniform way shows that hybrid logic
and hybrid-logical proof-theory is a natural enterprise.

Title:
An Introduction to Triangulated Categories
Abstract:
Homological Algebra is seemingly the most standard area of
category theory used in Mathematics. Though classically the
platform for homological algebra was an abelian category, recent
advanced results involve its 'cousin', a triangulated
category. In this talk, we will see briefly how the notions of
an abelian and a triangulated category appears, and open the
gate to the homological algebra.

SECOND ANNOUNCEMENT
====================================================================
SECOND INTERNATIONAL CONFERENCE ON ORDER ALGEBRA AND LOGICS

====================================================================
This meeting shares the goals of the conference with the same title,
held Nashville in June 2007, and continues the tradition of related
conferences in Prague, Novi Sad and Szeged.
Recent years have witnessed increased research activity on the
interface between logic and universal algebra. In particular, the use
of algebraic methods has proved to be fruitful in the study of
non-classical logics as well as in investigations related to the
constraint satisfaction problem. The purpose of the conference is to
bring together researchers from these fields to foster collaboration
and further research.
FEATURED AREAS
The featured areas include, but are not limited to, the following (in
alphabetical order):
- Algebraic logic
- Algorithmic problems in algebra
- Applications of universal algebra to logics
- Applications of universal algebra to the constraint satisfaction problem
- Complexity and other algorithmic problems
- Duality theory for algebraic structures
- Lattice theory
- Modal logics
- Non-classical logics
- Ordered algebraic structures
- Ordered sets
- Proof theory
- Residuated structures and substructural logics
- Tame congruence theory and applications
- Topological methods in algebra and logic
The scientific program consists of 50-minute plenary lectures, and
20-minute contributed talks.

Kobe Colloquium on Logic, Statistics and Informatics
以下の要領でコロクウィウムを開催します。
日時:2010年12月16日(木)15:10 〜
場所:神戸大学自然科学総合研究棟3号館4階421室(渕野グループプレゼンテーション室)
講演者:Dmitri Shakhmatov(愛媛大学)
題目:A Kronecker-Weyl theorem for subsets of abelian groups
アブストラクト:
Let N be the set of non-negative integer numbers, T the circle group and c
the cardinality of the continuum.
Given an abelian group G of size at most 2^c and a countable family F of
infinite subsets of G,
we construct ``Baire many'' monomorphisms pi: G to T ^c such that pi(E) is
dense in { y in T^c : ny=0 }
whenever n in N , E in F, nE = {0} and { x in E : mx=g } is finite for all g
in G and m such that
n = mk for some k in N \ {1} . We apply this result to obtain an algebraic
description of countable
potentially dense subsets of abelian groups, thereby making a significant
progress towards a
solution of a problem of Markov going back to 1944. A particular case of our
result yields a
positive answer to a problem of Tkachenko and Yaschenko (2002). Applications
to group actions and
discrete flows on T^cont, diophantine approximation, Bohr topologies and
Bohr compactifications
are also provided.

Title: Small-step and Big-step Aspects of Computation
(A Walk in the Semantic Park)
Abstract:
On the one hand, there are the De Morgan laws: it is clear how to
repeatedly apply them to put a proposition in, say, negational normal
form, with many small computational steps. On the other hand, such a
normal form can be obtained with one big computational step by
recursive descent.
On the second hand, there is the lambda-calculus: it is clear how to
repeatedly apply its contraction rules to put a lambda-term in, say,
weak-head normal form, if one exists, with many small computational
steps. On the other hand, such a normal form can be obtained with one
big computational step by recursive descent.
On the third hand, there are also abstract machines: state
transition systems that will obligingly yields normal forms as well,
if they exist.
There is no fourth hand in this talk: our goal is not to monkey with
computation, but to demonstrate a profound structural unity in the
various styles of semantic artifacts that have been proposed to
specify computation: as a calculus with a reduction strategy, as a
small-step system of proof rules, as a small-step system of reductions
in contexts, as a small-step abstract machine, as a big-step abstract
machine, as a continuation-passing big-step evaluation function, and
as a direct-style big-step evaluation function. In the course of this
talk, we will materialize this unity by using off-the-shelf program
transformations to constructively inter-derive semantic artifacts for
deterministic sequential programming languages, or, to be precise,
their representation as functional programs.

Title:
A Game of Arrows: Widely Interdisciplinary Research
Abstract:
Many of the most interesting problems in current scientific
research require interdisciplinary collaborations, spanning a
large number of disciplines. From cognitive science and systems
biology to environmental studies and challenges like critical
evaluations of alternative medicine, we need teams of specialists
to talk and work together. However, differences in culture and
methodology provide significant barriers for broadly
interdisciplinary collaborations. Each discipline has its own
approach to knowledge, but because this knowledge is shared
within the discipline, most researchers are not aware of the
hidden assumptions involved. It is a kind of tacit knowledge,
something you learn as a student, without any specific discussion
or critical analysis. What is needed for broadly
interdisciplinary studies is not only an increase in knowlege,
but rather a focus on knowlege of knowledge. What do we know
about the limits of how we know? This is the central question
that will be addressed in this lecture.
