SL(2,R)上Ricci流和交叉曲率流的后向性态

The Backward behavior of the Ricci and Cross Curvature Flows on SL(2,R)

Xiaodong Cao, John Guckenheimer, Laurent Saloff-Coste

摘要:

本文研究SL(2,R)型局部齐次三流形上的Ricci流和交叉曲率流的极大解的性质。我们证明,一般来说,一个极大解起源于一个海森堡型的次黎曼几何。这解决了两个作者在早期工作中留下的一个问题。

英文摘要:

This paper is concerned with properties of maximal solutions of the Ricci and cross curvature flows on locally homogeneous three-manifolds of type SL(2,R). We prove that, generically, a maximal solution originates at a sub-Riemannian geometry of Heisenberg type. This solves a problem left open in earlier work by two of the authors.
