Title: Freedom and boundaries

Abstract: I will outline recent results (joint with Anna Erschler) on the stabilizers of the group action on its Poisson boundary: existence of a free boundary action for any group with infinite conjugacy classes, a complete description of the possible kernels of such actions, and an example of a totally non-free boundary action.
