Faithful actions on generalized Furstenberg boundary

Operator Algebras 2024-04-23 v1

Abstract

Let GG be a countable discrete group that act minimally on a compact Hausdorff space XX by homeomorphisms. Our goal is to establish the equivalence between the faithfulness of the action of GG on the generalized Furstenberg boundary F(G,X)\partial_F(G, X) and a weakened version of the generalized Powers' averaging property. This result provides valuable insights into the state space of the crossed product C(X)rGC(X)\rtimes_{r}G.
