Title
Invariant Random Subgroups
Abstract
An invariant random subgroup is a probability measure on the space of closed subgroups of a locally compact group that is invariant under conjugation. Invariant random subgroups generalize normal subgroups and lattices, and arise naturally from measure-preserving group actions. In the talk, I will give an overview of the subject and present recent results on compact invariant random subgroups, joint with Cohen, Glöckner, and Lederle, and on ends of random subgroups, joint with Segev.
