Stationary boundaries on the space of amenable subgroups and C*-simplicity

Anna Cascioli, MartÃn Gilabert Vio, Eduardo Silva

We give a sufficient condition for a countable group $G$ to possess a probability measure $I^¼$ that admits a non-trivial $I^¼$ -boundary modeled in the space $\mathrm{Sub}_{\mathrm{a…

Continuity of asymptotic entropy on wreath products

Eduardo Silva

We prove the continuity of asymptotic entropy as a function of the step distribution for non-degenerate probability measures with finite entropy on wreath products $ A \wr B = \big…

The Poisson boundary of wreath products

Joshua Frisch, Eduardo Silva

We give a complete description of the Poisson boundary of wreath products $A ≀ B = ⨁_{B} A ⋊ B$ of countable groups $A$ and $B$ , for probability measures $I^¼$ with fin…

The CLT for lamplighter groups with an acylindrically hyperbolic base

Maksym Chaudkhari, Christian Gorski, Eduardo Silva

We prove a Central Limit Theorem for the drift of a non-elementary random walk with a finite exponential moment on a wreath product $A ≀ H = ⨁_{H} A ⋊ H$ with $A$ a non…

The Poisson boundary of Thompson's group $T$ is not the circle

MartÃn Gilabert Vio, Cosmas Kravaris, Eduardo Silva

Let $I^¼$ be a nondegenerate probability measure with finite entropy on a countable group $G \leq Homeo_{+} (S^{1})$ of orientation-preserving homeomorphisms of the circle actin…
