Boundary maps, germs and quasi-regular representations

Mehrdad Kalantar, Eduardo Scarparo

We investigate the tracial and ideal structures of $C^{*}$ -algebras of quasi-regular representations of stabilizers of boundary actions. Our main tool is the notion of boundary maps,…

On fixed point property for $L_{p}$ -representations of Kazhdan groups

Alan Czuron, Mehrdad Kalantar

Let $G$ be a topological group with finite Kazhdan set, let $Ω$ be a standard Borel space and $μ$ a finite measure on $Ω$ . We prove that for any $p \in [1, \infty)$ , any affine isom…

Noncommutative Furstenberg boundary

Mehrdad Kalantar, Paweł Kasprzak, Adam Skalski +1

We introduce and study the notions of boundary actions and of the Furstenberg boundary of a discrete quantum group. As for classical groups, properties of boundary actions turn out…
