Cardinality of Sets Under Determinacy

Abstract:
The axiom of determinacy (AD) is the assertion that any infinite game in which two players pick natural numbers to form an infinite sequence of natural numbers has a winning strategy for one of the two players. This talk will discuss infinitary combinatorics and its application to the study of the size or cardinality of infinite sets under the axiom of determinacy.
