Critical exponents of invariant random subgroups (Arie Levit, joint work with Ilya Gekhtman)
This lecture is a presentation of the preprint https://arxiv.org/abs/1804.02995. It will concern discrete invariant random subgroups in isometry groups of Gromov-hyperbolic spaces. In the case of rank one Lie groups essentially all IRSs are known to be discrete, but in general this is a nontrivial assumption.
