Wreath-like products of groups and their von Neumann algebras I: $W^{*}$ -superrigidity

Ionut Chifan, Adrian Ioana, Denis Osin +1

We introduce a new class of groups called wreath-like products. These groups are close relatives of the classical wreath products and arise naturally in the context of group theore…

$W^{}$ 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…

Cartan subalgebras in von Neumann algebras associated with graph product groups

Ionut Chifan, Srivatsav Kunnawalkam Elayavalli

In this short note we classify the Cartan subalgebras in all von Neumann algebras associated with graph product groups and their free ergodic measure preserving actions on probabil…
