中曲率流的奇异性分布

Singularity Profile in the Mean Curvature Flow

Weimin Sheng, Xu-Jia Wang

摘要:

本文研究了中曲率流的第一次奇点的几何性质。通过Huisken和Sinestrari的曲率捏挤估计,证明了欧几里得空间$\R^{n+1}$中具有正中曲率的超曲面的中曲率流是$κ$ -非坍缩的,并且爆破序列沿着子序列局部光滑地收敛到光滑的凸爆破解。作为结果,我们得到了平均凸流的一个局部Harnack不等式.

英文摘要:

In this paper we study the geometry of first time singularities of the mean curvature flow. By the curvature pinching estimate of Huisken and Sinestrari, we prove that a mean curvature flow of hypersurfaces in the Euclidean space $\R^{n+1}$ with positive mean curvature is $κ$-noncollapsing, and a blow-up sequence converges locally smoothly along a subsequence to a smooth, convex blow-up solution. As a consequence we obtain a local Harnack inequality for the mean convex flow.
