Logic Seminar
Percolation and invariant random subgroups
Yair Hartman,

I will illustrate an application of simple ideas from percolation to the study of invariant random subgroups (IRS). We use percolation to construct a continuum of IRSs on groups, for which we show that Furstenberg entropy varies continuously. For example, we obtain a short proof to the solution of the Furstenberg realization problem for the lamplighter group.
Joint work with Ariel Yadin.
