Relative solidity results and their applications to computations of some II factor invariants

Juan Felipe Ariza Mejia, Dulanji Nikethani Amaraweera, Ionut Chifan +1

In this paper we prove that whenever is hyperbolic relative to a family of exact, ressidually finite subgroups , the corresponding von Neumann algebra $\m…

McDuff and Prime von Neumann algebras arising from Thompson-Like Groups

Rolando de Santiago, Patrick DeBonis, Krishnendu Khan

In this paper we show that the cloning system construction of Skipper and Zaremsky [SZ21], under sufficient conditions, gives rise to Thompson-Like groups which are stable; in part…

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…

Examples of property (T) II factors with trivial fundamental group

Ionut Chifan, Sayan Das, Cyril Houdayer +1

In this article we provide the first examples of property (T) factors with trivial fundamental group, . Our examples arise as gro…

Subgroups of Lacunary Hyperbolic Groups and Free Products

Krishnendu Khan

A finitely generated group is lacunary hyperbolic if one of its asymptotic cones is an -tree. In this article we give a necessary and sufficient condition on lacunary h…

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…
