Invariant subalgebras of von Neumann algebras arising from negatively curved groups
Ionut Chifan, Sayan Das, Bin Sun
Using an interplay between geometric methods in group theory and soft von Neuman algebraic techniques we prove that for any icc, acylindrically hyperbolic group its von Neumann…

Semidirect product rigidity of group von Neumann algebras arising from class , inductive limits and fundamental group
Sayan Das, Krishnendu Khan
In this article we study property (T) groups arising from Rips construction in geometric group theory in the spirit of \cite{CDK19} and certain inductive limit groups from this cla…
