Abstract:

I will discuss some recent results and results in progress regarding actions of higher-rank lattices on tori, nil-manifolds, and boundaries. In particular, I will discuss a recent global rigidity result for Anosov actions on tori and nilmanifolds and some new partial results for local rigidity of affine actions. I’ll also discuss some local rigidity results in progress for actions on spheres and boundaries. This is joint work with Federico Rodriguez-Hertz and Zhiren Wang.
