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…

Unitary $L^{p +}$ -representations of almost automorphism groups

Antje Dabeler, Emilie Mai Elkiær, Maria Gerasimova +1

Let $G$ be a locally compact group with an open subgroup $H$ with the Kunze-Stein property, and let $π$ be a unitary representation of $H$ . We show that the representation $\wideti…

Spectral gap and origami expanders

Goulnara Arzhantseva, Dawid Kielak, Tim de Laat +1

We construct the first measure-preserving affine actions with spectral gap on surfaces of arbitrary genus $g > 1$ . We achieve this by finding geometric representatives of multi-twi…

Group $C^{*}$ -algebras of locally compact groups acting on trees

Dennis Heinig, Tim de Laat, Timo Siebenand

We study the group $C^{*}$ -algebras $C_{L^{p +}}^{*} (G)$ - constructed from $L^{p}$ -integrability properties of matrix coefficients of unitary representations - of locally compact groups…
