名古屋ロジックセミナー
http://www.math.mi.i.nagoya-u.ac.jp/~kihara/logic-seminar.html
日時:6月29日 (金) 15:30〜
場所:名古屋大学大学院情報学研究科棟 314室
講演者:Paul-Elliot Anglès D'Auriac (パリ・エスト・クレテイユ大学)
題目: On Infinite Time Turing Machine and and its related ordinals
アブストラクト:
In 1998, Hamkins and Lewis introduced Infinite Time Turing Machines (ITTMs), a version of Turing Machines where time is allowed to run through the ordinals instead of the integers. This model of computation revealed itself to have interesting connections with set theory and in particular Godel's constructible hierarchy. In this talk, we will be interested in the properties of the ordinals that naturally arises in the study of ITTMs, such as those that correspond to halting time, or that have a code that can be written on the tape of an ITTM.

Title: The concept of proof
Abstract:
The concept of proof is one of the most fundamental building blocks of
mathematics.
The Hilbertian revolution at the beginning of the 20th century is based
on an atomic
notion of proof which is the foundation of the axiomatic method:
"A proof is a finite sequence of formulas A1,..,An such that each Ai is
instance of
an axiom or follows by direct application of a rule from Ai1,..,Aik with
all ij<i."
No scientific revolution is however total, but there is a trend to
disregard all alternatives
to the successful method.
In this lecture we discuss more global notions of proof, where subproofs
are not necessarily
proofs themselves.
Examples are among others
1.protoproofs in the sense of Euler's famous solution to the Basel
problem, which
uses analogical reasoning and where additional external justifications
are necessary.
2.circular notions of proof, where the concept of proof itself
incooperates induction
3.sound proofs based on locally unsound rules
4.proofs based on abstract proof descriptions prominent e.g.
in Bourbaki, where only the choice of a suitable result makes a
verification possible.
We discuss the benefits of these alternative concepts and the
possibility that
innovative concepts of proof adapted to the problems in question might
lead to
strong mathematical results and constitute a novel area of Proof Theory.
