On Para-Sasakian Manifolds Satisfying Certain Curvature Conditions


U. C. De, Yanling Han, Krishanu Mandal




In this paper, we investigate Ricci pseudo-symmetric and Ricci generalized pseudo-symmetric $P$-Sasakian manifolds. Next we study $P$-Sasakian manifolds satisfying the curvature condition $S\cdot R=0$. Finally, we give an example of a 5-dimensional $P$-Sasakian manifold to verify some results.
