奇异黎曼叶理的中曲率流:非紧情形

On Mean curvature flow of Singular Riemannian foliations: Non compact cases

Marcos M. Alexandrino, Leonardo F. Cavenaghi, Icaro Gonçalves

摘要:

本文研究了以闭广义等参叶理的规则叶为初始数据的中曲率流(MCF),推广了Radeschi和第一作者的结果。我们证明了在有界曲率条件下,任何有限时间奇点都是一个奇异叶,且奇点是I型的。讨论了吸引区域的存在性,圆柱结构如何影响浸入子流形的基本MCF的收敛性,并对广义等参叶理的非闭叶的MCF作了一些讨论.

英文摘要:

In this paper we investigate the mean curvature flow (MCF) of a regular leaf of a closed generalized isoparametric foliation as initial datum, generalizing previous results of Radeschi and first author. We show that, under bounded curvature conditions, any finite time singularity is a singular leaf, and the singularity is of type I. We also discuss the existence of basin of attractions, how cylinder structures can affect convergence of basic MCF of immersed submanifolds and make a few remarks on MCF of non closed leaves of generalized isoparametric foliation.
