Sasakian流形的一般子流形的Frankel型定理

A Frankel type theorem for generic submanifolds of Sasakian manifolds

Dario Di Pinto, Antonio Lotta

摘要:

本文引入了Sasakian流形的一般子流形的一个较弱的概念,并在适当的假设下证明了这类子流形的Frankel型定理.它涉及到一般子流形和不变子流形之间的交以及两个一般子流形之间的交。从这个定理我们得到了Sasakian空间型的一般子流形的一些拓扑信息。

英文摘要:

We introduce a weaker notion of generic submanifold of a Sasakian manifold and we prove a Frankel type theorem for this kind of submanifolds under suitable hypotesis on the index of the scalar Levi forms determined by normal directions. It concerns the intersection between a generic and an invariant submanifold and the intersection between two generic submanifolds. From this theorem we derive some topological information about generic submanifolds of Sasakian space forms.
