Speaker: Joan Bagaria

Title: Berkeley Cardinals

Abstract: Berkeley cardinals are  large cardinals whose existence
contradicts the Axiom of Choice. We will  present some recent
results (joint with P. Koellner and W. H. Woodin) about the relative
position of Berkeley cardinals in the large cardinal hierarchy, and
also about the possible cofinalities of the first Berkeley cardinal.
