Abstract: For Riemannian manifolds and spacetimes with certain asymptotics at infinity there is a rather unique invariant called mass, first discovered in General Relativity. The so called rigidity theorems describe what happens when the mass vanishes. In this talk we will address the related question: what happens when the mass is small? How do Riemannian manifolds and spacetimes converge when the mass goes to zero? We study this question with respect to different notions of convergence.
