$W^{}$ and $C^{}$ -superrigidity results for coinduced groups

Ionut Chifan, Alec Diaz-Arias, Daniel Drimbe

In this paper we explore a generic notion of superrigidity for von Neumann algebras $L (G)$ and reduced $C^{*}$ -algebras $C_{r}^{*} (G)$ associated with countable discrete groups $G$ . This…

New examples of W $^{}$ and C $^{}$ -superrigid groups

Ionut Chifan, Alec Diaz-Arias, Daniel Drimbe

A group $G$ is called $W^{*}$ -superrigid (resp. $C^{*}$ -superrigid) if it is completely recognizable from its von Neumann algebra $L (G)$ (resp. reduced $C^{*}$ -algebra $C_{r}^{*} (G)$ ). Devel…
