## Primeness of Generalized Wreath Product von Neumann Algebras

##### Abstract:

In this talk we'll investigate the primeness of generalized wreath product II1 factors using techniques from deformation/rigidity theory. We give general conditions relating tensor decompositions of generalized wreath products to stabilizers of the associated group action, and use this to find new examples of prime II1 factors.

Hosts: David Jekel and Priyanga Ganesan
