局部齐次三流形上的向后里奇流

Backward Ricci Flow on Locally Homogeneous Three-manifolds

Xiaodong Cao, Laurent Saloff-Coste

摘要:

本文研究了局部齐次三维流形上的向后里奇流。我们描述了长时间的行为,并表明,通常和适当的重新缩放后,有收敛到一个子黎曼几何。作者在交叉曲率流的情况下也观察到类似的行为。

英文摘要:

In this paper, we study the backward Ricci flow on locally homogeneous 3-manifolds. We describe the long time behavior and show that, typically and after a proper re-scaling, there is convergence to a sub-Riemannian geometry. A similar behavior was observed by the authors in the case of the cross curvature flow.
