$C^{*}$ -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…

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 $μ$ a probability measure on $G$ . We build a new framework to compute asymptotic quantities associated with the $μ$ -random walk on $G$ , using metho…

Topological Boundaries of Representations and Coideals

Benjamin Anderson-Sackaney, Fatemeh Khosravi

For a locally compact quantum group $G$ , a (left) coideal is a (left) $G$ -invariant von Neumann subalgebra of $L^{\infty} (G)$ . We introduce and analyze var…
