里奇流下的质量

Mass under the Ricci flow

Xianzhe Dai, Li Ma

摘要:

本文研究ALE空间的ADM质量沿里奇流的变化。因此,我们首先表明,ALE性质下保持里奇流。然后,我们证明了在三维流动下质量是不变的(类似的结果在更高维的更多的假设下成立)。这一结果的一个结果如下。设$(M,g)$是维数为$n=3$的ALE流形.如果$m(g)\neq 0$,则从$g$开始的里奇流不能有欧几里得空间作为其(一致)极限。

英文摘要:

In this paper, we study the change of the ADM mass of an ALE space along the Ricci flow. Thus we first show that the ALE property is preserved under the Ricci flow. Then, we show that the mass is invariant under the flow in dimension three (similar results hold in higher dimension with more assumptions). A consequence of this result is the following. Let $(M,g)$ be an ALE manifold of dimension $n=3$. If $m(g)\neq 0$, then the Ricci flow starting at $g$ can not have Euclidean space as its (uniform) limit.
