奇异里奇流I

Singular Ricci flows I

Bruce Kleiner, John Lott

摘要:

我们引入奇异里奇流,这是里奇流时空受到一定的渐近条件。我们考虑了从一个固定的紧致黎曼三维流形出发的带有手术的里奇流,当手术参数变化时的行为。我们证明了当手术参数趋于零时,带手术的流动子收敛于奇异里奇流。我们建立了奇异里奇流的一些几何和分析性质。

英文摘要:

We introduce singular Ricci flows, which are Ricci flow spacetimes subject to certain asymptotic conditions. We consider the behavior of Ricci flow with surgery starting from a fixed initial compact Riemannian 3-manifold, as the surgery parameter varies. We prove that the flow with surgery subconverges to a singular Ricci flow as the surgery parameter tends to zero. We establish a number of geometric and analytical properties of singular Ricci flows.
