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.

Computability Theory and Foundations of Mathematics (CTFM) aims to
develop computability theory and logical foundations of Mathematics.
The scope involves the topics Computability Theory, Reverse
Mathematics, Nonstandard Analysis, Proof Theory, Set Theory,
Philosophy of Mathematics, Constructive Mathematics, Theory of
Randomness and Computational Complexity Theory.
We will call for the contributed talks later.
