Classification of right-angled Coxeter groups with a strongly solid von Neumann algebra

Matthijs Borst, Martijn Caspers

Let $W$ be a finitely generated right-angled Coxeter group with group von Neumann algebra $L (W)$ . We prove the following dichotomy: either $L (W)$ is strongly so…

A Sobolev estimate for radial $L^{p}$ -multipliers on a class of semi-simple Lie groups

Martijn Caspers

Let $G$ be a semi-simple Lie group in the Harish-Chandra class with maximal compact subgroup $K$ . Let $Ω_{K}$ be minus the radial Casimir operator. Let $\frac{1}{4} \dim(G/K) < S_G <…
