单位球中Moebius截曲率的内蕴性
The characterization of Moebius sectional curvature in unit sphere
【摘要】 设x:Mm→Sn为Sn中无脐点子流形,K为截曲率的下确界,本文给出截曲率两个拼挤定理。
【Abstract】 In this paper, let Mm be a m-dimensional submanifold without umbilic point in unit sphere, we prove two pinching theorems about Moebius sectional curvature, which give the characterizations of Clifford tori,Veronese submanifolds by the Moebius invariants.
