Higher rigidity properties of locally symmetric spaces

Abstract

We know that certain types of locally symmetric spaces are (very) rigid. What about Riemannian manifolds that look locally symmetric 99% of the time?

Rigidity phenomena for these types of spaces are related to higher property (T), representation stability and the existence of a non-sofic group. Not much is known, but I will describe one result in this direction: a rigidity theorem for branched covers of octonionic hyperbolic manifolds with small branching locus. Based on a joint work with Ben Lowe.
