Some Applications of Group Theoretic Rips Constructions to the Classification of von Neumann Algebras
Ionut Chifan, Sayan Das, Krishnendu Khan
In this paper we study various von Neumann algebraic rigidity aspects for the property (T) groups that arise via the Rips construction developed by Belegradek and Osin in geometric…

Rigidity results for von Neumann algebras arising from mixing extensions of profinite actions of groups on probability spaces
Ionut Chifan, Sayan Das
Motivated by Popa's seminal work \cite{Po04}, in this paper, we provide a fairly large class of examples of group actions satisfying the extended Neshveyev-St…
