我们在子流形理论和切触几何之间架起了一座桥梁。本文从文献[3]的结果出发,给出了Sasakian、Nearly Sasakian、Kcontact等基本概念的几何意义(定理1)。此外,在非平坦复空间形式中的全η-脐超曲面概念的启发下,我们给出了切触几何中的一个新概念(定理2).
We bridge between submanifold theory and contact geometry. We give a geometric meaning of some fundamental notions such as Sasakian, nearly Sasakian, Kcontact from the viewpoint of the result in [3] (Theorem 1). Moreover, motivated by the notion of totally η-umbilic hypersurfaces in a nonflat complex space form, we give a new notion in contact geometry (Theorem 2).
