摘要

从Perelman的工作中可以知道，紧致三流形上Ricci流的任何有限时间奇异性都是在一个古老的$\kappa$-解上建模的。我们证明了维数$3$中的每一个非紧古$\kappa$-解与收缩圆柱体（或其商）或Bryant孤立子是等距的。

Ancient solutions to the Ricci flow in dimension $3$

It is known from work of Perelman that any finite-time singularity of the Ricci flow on a compact three-manifold is modeled on an ancient $\kappa$-solution. We prove that the every noncompact ancient $\kappa$-solution in dimension $3$ is isometric to either the shrinking cylinders (or a quotient thereof), or the Bryant soliton.
