Title:Determinacy of Wadge classes and subsystems of second-order arithmetic
Seminar:Logic Seminar
Speaker:Takako Nemoto, JAIST, Japan
Abstract:
I will discuss determinacy schemata motivated by Wadge hierarchy, which is finer than Borel hierarchy, and the hierarchy of them in second-order arithmetic. I will introduce characterizations of subsystems of second-order arithmetic, not only the Big Five systems, but also relatively minor systems, by determinacy schemata.
