| Abstract: | Popa's deformation/rigidity theory led to numerous classification and structure theorems for von Neumann algebras coming from groups and their actions on measure spaces. Negative curvature phenomena like hyperbolicity have played a key role in several of these results. I will first give an introduction to von Neumann algebras and then present a number of rigidity theorems, highlighting the usage of negative curvature type concepts. |
