摘要

In this research paper, we analyze a non-invariant hypersurfaces of a quasi-para-Sasakian manifold with \((f, g, u, v, \lambda )\) -structure. The paper is divided into two sections. In the first section the properties of non-invariant hypersurfaces of a quasi-para-Sasakian manifold with \(\left(f, g, u, v, \lambda \right)\) -structure are discussed. In second section, the necessary and sufficient condition for totally umbilical non-invariant hypersurfaces equipped with \((f, g, u, v, \lambda )\) -structure of a quasi-para-Sasakian manifold to be totally geodesic has been explored.
