Geometry of Hypersurfaces of a Semi Symmetric Semi Metric Connection in a Quasi-Sasakian Manifold

The existence of the structure vector field implies some important changes. The purpose of the paper is to study the notion of CR-submanifold and the existence of some structures on a hypersurface of a semi symmetric semi metric connection in a quasi-Sasakian manifold.结构向量场（structure vector field）的存在性蕴含着若干重要的变化。本文旨在研究拟萨萨金流形（quasi-Sasakian manifold）中配备半对称半度量联络（semi symmetric semi metric connection）的超曲面（hypersurface）上的CR子流形（CR-submanifold）概念，以及其上若干结构的存在性。
