Compact Gradient Shrinking Ricci Solitons with Positive Curvature Operator
arXiv:math/0601599
Abstract
In this paper, we study the following conjecture of Hamilton: Any compact gradient shrinking Ricci soliton with positive curvature operator must be Einstein. We first derive several identities. Then we show that the conjecture is true under an additional condition. Furthermore, such a soliton must be of constant curvature.
