Non-Wiener groups with a Gelfand pair

Max Carter, Jared T. White

Let $G$ be a non-amenable locally compact group and $K$ a compact subgroup of $G$ such that $(G, K)$ is a Gelfand pair. We show that if $G$ admits a suitable boundary representation…

Radicals of Biduals of Beurling Algebras Can Be Different for the Two Arens Products

Jared T. White

Let $rad$ denote the Jacobson radical of a Banach algebra, and let $□$ and $◊$ denote the two Arens products on its bidual. We give an example of a Beurlin…

Weak*-Simplicity of Convolution Algebras on Discrete Groups

Jared T. White

We prove that, given a discrete group $G$ , and $1 \leq p < \infty$ , the algebra of $p$ -convolution operators $C V_{p} (G)$ is weak*-simple, in the sense of having no non-trivial weak*-…
