Introduction to Invariant Random Subgroups
Abstract: An Invariant Random Subgroup (IRS for short) for a group $G$ is a probability measure on the space ${\rm Sub}_G$ of all closed subgroups of $G$, invariant under the natural $G$-action by conjugation. This concept is a simultaneous generalization of closed normal subgroups and of lattices.
In the lecture we will discuss the compact space ${\rm Sub}_G$, and IRS and give some basic properties of those.
