## Some rigidity results for Ricci-flat manifolds and gradient steady Ricci solitons

##### Abstract:

Gradient steady Ricci solitons are potential singularity models for the Ricci flow. Also, they are natural generalizations of Ricci-flat manifolds, hence share many interesting properties. In this talk I'll present some $\epsilon$-rigidity results for noncompact Ricci-flat manifolds and the generalization to gradient steady Ricci solitons.
