Abstract/Media

Recent works have achieved  classification or global rigidity of “higher rank” actions in  a number of situations.   I will discuss and hopefully explain some of the key underlying  ideas.   In particular, I will discuss  work with A. Gorodnik on rigidity of smooth factors of projective actions.
