Weak* tensor products for von Neumann algebras

Matthew Wiersma

The category of $C^{*}$ -algebras is blessed with many different tensor products. In contrast, virtually the only tensor product ever used in the category of von Neumann algebras is t…

On exotic group C*-algebras

Zhong-Jin Ruan, Matthew Wiersma

Let $Γ$ be a discrete group. A $C^{*}$ -algebra $A$ is an exotic $C^{*}$ -algebra (associated to $Γ$ ) if there exist proper surjective $C^{*}$ -quotients $C^{*} (Γ) \to A \to C_{r}^{*} (Γ)$ . In this…
