关于En+1中全臍超曲面和极小超曲面的一个注记
A Note on the Totally Umbilical and minimal Hypersurfaces in
【摘要】 本文利用改进了的一般极大值原理,给出了n+1维欧氏空间En+1中利齐曲率下方有界的完备连通超曲面为全脐超曲面或极小超曲面的一个充要条件。
【Abstract】 In this paper, the improved general maximum principles are used to give the necessary and sufficient conditions for a complete connected hypersurface V" with Ricci curvature lower bounded to be a totally umbilical or a minimal hypersurface in the n+1 dimentional Euclidean space En+1.
