-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 -simplicity of discrete quantum groups via the theory of boundary actions. In…

Maximal amenability of the radial subalgebra in free quantum group factors
Roland Vergnioux, Xumin Wang
We show that the radial MASA in the orthogonal free quantum group algebra L(FO_N) is maximal amenable if N is large enough, using the Asymptotic Orthogonality Property. This relies…
