Title: Classification of crossed product C*-algebras arising from essentially free actions

Abstract: Essentially free actions play an important role in ergodic theory and group measure space II1-factors. In this talk, I will explain why (uniform) essential freeness is a better prerequisite than topological freeness in the classification of crossed product C*-algebras, and provide a first general result on uniform property Γ and Z-stability, assuming only topological freeness, in this direction.
