-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…

Hecke algebras and the Schlichting completion for discrete quantum groups

Adam Skalski, Roland Vergnioux, Christian Voigt

We introduce Hecke algebras associated to discrete quantum groups with commensurated quantum subgroups. We study their modular properties and the associated Hecke operators. In ord…

K-amenability for amalgamated free products of amenable discrete quantum groups

Roland Vergnioux

The basic notions and results of equivariant KK-theory concerning crossed products can be extended to the case of locally compact quantum groups. We recall these constructions and…

The Property of Rapid Decay for Discrete Quantum Groups

Roland Vergnioux

We introduce the Property of Rapid Decay for discrete quantum groups by equivalent characterizations that generalize the classical ones. We then investigate examples, proving in pa…

Orientation of quantum Cayley trees and applications

Roland Vergnioux

We introduce the quantum Cayley graphs associated to quantum discrete groups and study them in the case of trees. We focus in particular on the notion of quantum ascending orientat…
