An introduction to deformation/rigidity theory and the classification of II_1 factors
Sorin Popa's deformation/rigidity theory has provided a wealth of deep classification theorems for von Neumann algebras. I will introduce the basic principles of this theory and then focus on the classification of crossed product von Neumann algebras arising from actions of the free groups.
