中曲率流讲座

Lectures on mean curvature flow

Robert Haslhofer

摘要:

如果超曲面族中每一点的速度由中曲率向量给出,则超曲面族通过中曲率流演化。中曲率流动是外几何中最自然的发展方程,自Brakke和Huisken的开创性工作以来得到了广泛的研究。在过去的15年里,怀特发展了一个意义深远的规则性和结构理论的平均凸中曲率流,和Huisken-Sinestrari建立了一个流与手术的两个凸超曲面。在这门课程中,我首先对超曲面的中曲率流做了一个一般性的介绍,然后与Bruce Kleiner合作,对White和Huisken-Sinestrari的理论进行了精简和统一的处理。这些笔记来自KIAS首尔和SNS比萨的暑期学校。

英文摘要:

A family of hypersurfaces evolves by mean curvature flow if the velocity at each point is given by the mean curvature vector. Mean curvature flow is the most natural evolution equation in extrinsic geometry, and has been extensively studied ever since the pioneering work of Brakke and Huisken. In the last 15 years, White developed a far-reaching regularity and structure theory for mean convex mean curvature flow, and Huisken-Sinestrari constructed a flow with surgery for two-convex hypersurfaces. In this course, I first give a general introduction to the mean curvature flow of hypersurfaces and then present joint work with Bruce Kleiner, where we give a streamlined and unified treatment of the theory of White and Huisken-Sinestrari. These notes are from summer schools at KIAS Seoul and SNS Pisa.
