Query: A view on Invariant Random Subgroups and Lattices   For more than half a century lattices in Lie groups played an important role
in geometry, number theory and group theory. Recently the notion of Invariant
Random Subgroups (IRS) emerged as a natural generalization of lattices. It is
thus intriguing to extend results from the theory of lattices to the context of
IRS, and to study lattices by analyzing the compact space of all IRS of a given
group. This article focuses on the interplay between lattices and IRS, mainly
in the classical case of semisimple analytic groups over local fields.
