Title: Two results on rigidity of commutative actions by toral automorphisms
Speaker: Zhiren Wang
Speaker Info: Princeton University
Brief Description:
Special Note:

In 1983 Berend proved rigidity of higher-rank commutative actions by toral automorphisms under some hyperbolicity and irreduciblity assumptions. We will present two rigidity results that respectively extend Berend's theorem to certain non-hyperbolic and reducible cases. We will also discuss some counterexamples of non-homogeneous orbit closures. This is joint work with Elon Lindenstrauss.
