里奇流的Einstein度量和保曲率条件

Einstein metrics and preserved curvature conditions for the Ricci flow

S. Brendle

摘要:

设C是代数曲率张量空间中的锥。此外,设(M,g)是紧致Einstein流形,且(M,g)的曲率张量在M上的每一点都位于锥C中.证明了当锥C满足一定的结构条件时,(M,g)具有常截面曲率.

英文摘要:

Let C be a cone in the space of algebraic curvature tensors. Moreover, let (M,g) be a compact Einstein manifold with the property that the curvature tensor of (M,g) lies in the cone C at each point on M. We show that (M,g) has constant sectional curvature if the cone C satisfies certain structure conditions.
