SUMMARY:ACC Seminar: Some Open Problems on Invariant Random Subgroups.
DESCRIPTION:ABSTRACT
Let G be a countably infinite group and let Sub_G be the compact space of subgroups H ⩽ G. Then an invariant random subgroup (IRS) of G is a probability measure ν on Sub_G which is invariant under the conjugation action of G on Sub_G. In particular, if ν is ergodic, then ν is a notion of randomness on Sub_G with a 0-1 law for every group-theoretic property. In this talk, after a brief introduction to the theory of invariant random subgroups, I will discuss some of the many open questions in this relatively new area of group theory.
