$L^{p}$ -Fourier and Fourier-Stieltjes algebras for locally compact groups

Matthew Wiersma

Let $G$ be a locally compact group and $1 \leq p < \infty$ . A continuous unitary representation $π : G \to B (H)$ of $G$ is an $L^{p}$ -representation if the matrix coefficient…

C-norms for tensor products of discrete group C-algebras

Matthew Wiersma

Let $Γ$ be a discrete group. We show that if $Γ$ is nonamenable, then the algebraic tensor products $C_{r}^{*} (Γ) \otimes C_{r}^{*} (Γ)$ and $C^{*} (Γ) \otimes C_{r}^{*} (Γ)$ do not admit unique $C^*…

Exotic group C*-algebras

Matthew Wiersma

Let $Γ$ be a discrete group. When $Γ$ is nonamenable, the reduced and full group $C$ *-algebras differ and it is generally believed that there should be many intermediate $C$ *-algeb…
