曲面上里奇流的紧致古解的分类

Classification of compact ancient solutions to the Ricci flow on surfaces

Panagiota Daskalopoulos, Richard Hamilton, Natasa Sesum

摘要:

我们考虑紧致曲面上里奇流的一个古老解$g(\cdot,t)$,它存在于$t\in (-\infty,T)$中,并在时间$t=T$变为球形.我们证明了度量$g(\cdot,t)$是一个家庭的收缩领域,这是一个I型古老的解决方案,或Rosenau解决方案,这是一个II型古老的解决方案。

英文摘要:

We consider an ancient solution $g(\cdot,t)$ of the Ricci flow on a compact surface that exists for $t\in (-\infty,T)$ and becomes spherical at time $t=T$. We prove that the metric $g(\cdot,t)$ is either a family of contracting spheres, which is a type I ancient solution, or a Rosenau solution, which is a type II ancient solution.
