Title:Geometry of Ricci solitons
Seminar:Department of Mathematics Colloquium
Speaker:Huai-Dong Cao, Lehigh University
Abstract:
Self-similar solutions play an important role in the study of geometric flows, as they often arise as singularity models. For Hamilton's Ricci flow, self-similar solutions are called Ricci solitons. They are natural generalizations of Einstein metrics. They can be viewed as fixed points of the Ricci flow as a dynamical system on the space of Riemannian metrics modulo diffeoeomorphisms and scalings. They are also critical points of the geometric functionals found by Perelman and others. In this talk, we shall first describe briefly self-similar solutions of the curve-shortening flow and the mean curvature flow, and then discuss some recent developments on the geometry of Ricci solitons.
