Abstract:

Ricci solitons are self-similar solutions to Hamilton’s Ricci flow and a natural extension of Einstein manifolds. They often arise as singularity models in the Ricci flow. In this talk I shall describe some recent progress on shrinking Ricci solitons, especially 4-dimensional ones with half positive isotropic curvature.
