An invariant random subgroup in a (finitely generated) group is a
probability measure on the space of subgroups of the group invariant under
the inner automorphisms of the group. It is a natural generalization of the
the notion of normal subgroup. I’ll give an introduction into this actively
developing subject and then discuss in more detail examples of invariant
random subgrous in groups of intermediate growth. The last part of the talk
will be based on a recent joint work with Mustafa Benli and Rostislav
Grigorchuk.
