Towards a New Theory of Bounded Arithmetic for PSPACE computations

Presented by: 
N Eguchi Tohoku University
Date: 
Wednesday 28th March 2012 - 11:00 to 11:30
Venue: 
INI Seminar Room 1
Abstract: 
I will present a second order extension of well-known first order theories of bounded arithmetic. The purpose of this work is to find a new proof-theoretic characterisation of the polynomial-space computable functions in terms of bounded arithmetic. This is a joint work with Toshiyasu Arai (Chiba University, Japan) in progress.
