WebThis thesis studies canonical metrics on Riemannian manifolds. It consists of two parts. In the first part, we study Einstein four-manifolds with 3-positive curvature operator. We prove that if the curvature operator is 3-positive, then the sectional curvature has a positive lower bound which depends only on the Einstein constant; we also partially improve results of … WebJan 1, 2006 · This question was finally answered by Brendle and Schoen [9]via the Ricci flow. Another important differential sphere theorem via Ricci flow is due to Böhm and Wilking [4]. They proved that ...
