Some and -rigidity results for actions by wreath product groups
Ionut Chifan, Sorin Popa, James Owen Sizemore
We use deformation-rigidity theory in von Neumann algebra framework to study probability measure preserving actions by wreath product groups. In particular, we single out large fam…

On the structural theory of II_1 factors of negatively curved groups, II: Actions by product groups
Ionut Chifan, Thomas Sinclair, Bogdan Udrea
This paper includes a series of structural results for von Neumann algebras arising from measure preserving actions by product groups on probability spaces. Expanding upon the meth…

On the structural theory of factors of negatively curved groups
Ionut Chifan, Thomas Sinclair
Ozawa showed that for any i.c.c., hyperbolic group, the associated group factor is solid. Developing a new approach that combines some methods of Peterson, Ozawa and Popa, and Ozaw…
