Pálfy Máté: On various notions of universally Baire sets

ELTE Analízis tanszék szemináruma

Abstract: Universally Baire sets play a crucial role in set theory, and they are
also very interesting from the point of view of descriptive set
theory. However, there are at least a dozen different definitions, and
many of these are non-equivalent (at least consistently). The
goal of this talk is to clarify this situation, and also to give
applications in the theory of so called Haar meagre sets. Joint work
with Márton Elekes.
