中曲率流的凸性估计(英文)

中曲率流是非常重要的几何发展方程.给出Huisken和Sinestrasi关于中凸超曲面上中曲率流的凸性估计的一个重要结果的评注.

Sasakian Submanifolds of Kaehlerian Manifolds(Ⅱ)

In this paper,it is proved that the Sasakian anti-holomorphic submanifolds of a Kaehlerian manifold is characterized by D-totally umbilical,and some curvature properties of the CR-submanifolds are ohtained.
