Faithful actions on generalized Furstenberg boundary (2404.13436v1)
Published 20 Apr 2024 in math.OA
Abstract: Let $G$ be a countable discrete group that act minimally on a compact Hausdorff space $X$ by homeomorphisms. Our goal is to establish the equivalence between the faithfulness of the action of $G$ on the generalized Furstenberg boundary $\partial_F(G, X)$ and a weakened version of the generalized Powers' averaging property. This result provides valuable insights into the state space of the crossed product $C(X)\rtimes_{r}G$.
