Mostow Rigidity Made Easier

Geometric Topology 2026-04-20 v5

Abstract

This article gives a self-contained proof of Mostow Rigidity, at least modulo undergrad real analysis. The proof should be accessible to grad students interested in geometry and topology. It has no new research, but I think that this is an unusually clean and analytically light proof of this famous result. I am posting this because I think it will be useful to geometry/topology students.

Comments

This version is very close to the previous one. I edited it according to a referee report. This will very likely appear as an article in the Bulletin of the A.M.S
