Title: Mostow rigidity: when topology determines geometry

Abstract: Generally, topology is more "flexible" than geometry---isometric spaces are homeomorphic, but not vice-versa. One exception is known as Mostow rigidity: in dimensions 3 and higher, closed hyperbolic manifolds are isometric if and only if their fundamental groups are isomorphic. I will discuss Mostow's theorem, sketch a proof, and (time permitting) explain why the proof fails in dimension 2.

 

Note: The talk will start at 4:10 pm
