Co-induction and invariant random subgroups
Alekos Kechris, Department of Mathematics, Caltech,
I will discuss a notion of co-induction for invariant random subgroups and show how it can be used to construct new collections of continuum many non-atomic, weakly mixing invariant random subgroups for various classes of groups. I will also discuss an application to the problem of continuity of the co-induction operation on pmp actions. This is joint work with Vibeke Quorning.
