Title:
Destroying rank one factors and a counterexample to the Katok-Spatzier conjecture

Speaker:
Kurt Vinhage

Abstract:
I will discuss rank one factors of abelian group actions and their interaction with transitivity and expansion properties for restrictions of the action. I will then describe a construction which provides a counterexample to the Katok-Spatzier conjecture.
