Entropies and Poisson boundaries of random walks on groups with rapid decay

Benjamin Anderson-Sackaney, Tim de Laat, Ebrahim Samei +1

Let $G$ be a countable group and $I^¼$ a probability measure on $G$ . We build a new framework to compute asymptotic quantities associated with the $I^¼$ -random walk on $G$ , using met…

$C^{*}$ -simplicity and boundary actions of discrete quantum groups

Benjamin Anderson-Sackaney, Roland Vergnioux

We introduce and investigate several quantum group dynamical notions for the purpose of studying $C^{*}$ -simplicity of discrete quantum groups via the theory of boundary actions. In…
