Rigidity of gradient Ricci Solitons

Differential Geometry 2007-10-18 v1

Abstract

We define a gradient Ricci soliton to be rigid if it is a flat bundle % N\times_{\Gamma}\mathbb{R}^{k} where NN is Einstein. It is known that not all gradient solitons are rigid. Here we offer several natural conditions on the curvature that characterize rigid gradient solitons. Other related results on rigidity of Ricci solitons are also explained in the last section.
