David Schrittesser: News on mad families

KGRC Research Seminar  – 2017-06-22 at 4pm. Speaker: David Schrittesser (University of Copenhagen, Denmark) Abstract: This talk is about two results on mad families (dating from this year): Firstly, in joint work with Karen Bakke Haga and Asger Törnquist and, we link madness of certain definable sets to forcing and use this to show that under the Axiom of Projective Determinacy there are no projective mad families. continue reading…
