Title: Unsound inferences make proofs shorter
Abstract:
…
[View More]We give examples of calculi that extend Gentzen's sequent calculus LK in
such a way that
(i) derivations lead only to true sequents
(ii) cut free proofs may be non-elementary shorter than cut free LK proofs.

1st Call for Papers
The Sixth International Conference on Logic, Rationality and
Interaction (LORI-VI)
September 11-14, 2017, Hokkaido University, Sapporo, Japan
Submission deadline: March 31, 2017
The International Conference on Logic, Rationality and Interaction
(LORI) conference series aims at bringing …
[View More]together researchers working
on a wide variety of logic-related topics that concern the
understanding of rationality and interaction. The series aims at
fostering a view of Logic as an interdisciplinary endeavour, and
supports the creation of an East-Asian community of interdisciplinary
researchers.
We invite submission of contributed papers on any of the broad themes
of LORI series; specific topics of interest include, but are not
limited to, formal approaches to
- agency
- argumentation and agreement
- belief representation
- cooperation
- belief revision and belief merging
- strategic reasoning
- games
- decision making and planning
- knowledge and action
- epistemology
- dynamics of informational attitudes
- speech acts
- knowledge representation
- interaction
- norms and normative systems
- natural language
- rationality
- philosophy and philosophical logic
- preference and utility
- social choice
- probability and uncertainty
- social interaction
- intentions, plans, and goals
Submitted papers should be at most 12 pages long, with one additional
page for references, in PDF format following the Springer LNCS style.
Please submit your paper by Friday March 31, 2017, via EasyChair (
http://easychair.org/conferences/?conf=lori6 ). Accepted papers will
be collected as a volume in the FoLLI Series on Logic, Language and
Information, and authors may be later invited to submit extended
versions of their papers in a special issue of a prestigious journal.

題目:
Paraconsistent set theory and inconsistent mathematics
概要:
Paraconsistent set theory takes as axiomatic the `naive' comprehension
principle that every collection forms a set. The infamous paradoxes are
then just theorems. The background logic that makes this coherently
possible is substantially …
[View More]weaker than classical logic; but the expressive
power of the theory is substantially stronger than classical set theory.
With these competing forces in the background, we will look at two
interrelated goals:
Recapture -- reassurance that nothing too important mathematically is lost
Expansion -- where new insights and results are gained, studying novel
mathematical objects not visible with any other theory
I will survey the development of paraconsistent set theory, showing how the
basic properties of ordinal and cardinal numbers can be established, along
with new perspectives on `proper classes', the axiom of choice, and the
continuum hypothesis. With this foundation, I will mention some further
work in inconsistent mathematics: from computability theory, arithmetic,
analysis, and topology. Throughout I will call attention to the challenges
that this research program faces.

CALL FOR PAPERS
WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers. The twenty-fourth WoLLIC will be held at the School of Electronic Engineering and Computer Science, Queen Mary College, London, UK, from July 18th to 21st, 2017. It is sponsored by the Association for Symbolic Logic (ASL), the Interest Group in Pure and Applied Logics (IGPL), the The Association for Logic, Language and Information (FoLLI), the European Association for Theoretical Computer Science (EATCS), the European Association for Computer Science Logic (EACSL), the Sociedade Brasileira de Computação (SBC), and the Sociedade Brasileira de Lógica (SBL).
PAPER SUBMISSION
Contributions are invited on all pertinent subjects, with particular interest in cross-disciplinary topics. Typical but not exclusive areas of interest are: foundations of computing and programming; novel computation models and paradigms; broad notions of proof and belief; proof mining, type theory, effective learnability; formal methods in software and hardware development; logical approach to natural language and reasoning; logics of programs, actions and resources; foundational aspects of information organization, search, flow, sharing, and protection; foundations of mathematics; philosophy of mathematics; philosophical logic. Proposed contributions should be in English, and consist of a scholarly exposition accessible to the non-specialist, including motivation, background, and comparison with related works. Articles should be written in the LaTeX format of LNCS by Springer (see authors instructions at http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0 <http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0>). They must not exceed 12 pages, with up to 5 additional pages for references and technical appendices. The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings. It is expected that each accepted paper be presented at the meeting by one of its authors. Papers must be submitted electronically at the WoLLIC 2017 EasyChair website. (Please go to http://wollic.org/wollic2017/instructions.html <http://wollic.org/wollic2017/instructions.html> for instructions.) A title and single-paragraph abstract should be submitted by Mar 14, 2017, and the full paper by Mar 21, 2017 (firm date). Notifications are expected by Apr 22, 2017, and final papers for the proceedings will be due by May 6, 2017 (firm date).
PROCEEDINGS
The proceedings of WoLLIC 2017, including both invited and contributed papers, will be published in advance of the meeting as a volume in Springer's LNCS series. In addition, abstracts will be published in the Conference Report section of the Logic Journal of the IGPL, and selected contributions will be published as a special post-conference WoLLIC 2017 issue of a scientific journal (to be confirmed).
