共形场与高阶中曲率为常数的叶片的稳定性

Conformal fields and the stability of leaves with constant higher order mean curvature

Krzysztof Andrzejewski, Pawel Walczak

摘要:

本文研究了具有常数$S_r$ th中曲率的子流形$S_r$ .我们调查,这种子流形的稳定性的情况下,当他们是一个余维一叶理的叶子。本文还将Barros-Sousa和Alías-Colares关于共形场的最新结果推广到任意流形上.利用这一点,我们证明了Killing场的法向分量是具有$S_{r+1}$常数的子流形的$r$阶Jacobi场.最后,研究了保叶理的$r$阶Jacobi场与向量场之间的关系.

英文摘要:

In this paper, we study submanifolds with constant $r$th mean curvature $S_r$. We investigate, the stability of such submanifolds in the case when they are leaves of a codimension one foliation. We also generalize recent results by Barros - Sousa and Alías - Colares, concerning conformal fields, to an arbitrary manifold. Using this we show that normal component of a Killing field is a $r$th Jacobi field of a submanifold with $S_{r+1}$ constant. Finally, we study relations between $r$th Jacobi fields and vector fields preserving a foliation.
