On (∈) - Lorentzian para-Sasakian Manifolds.

The object of this paper is to study (∈)-Lorentzian para-Sasakian manifolds. Some typical identities for the curvature tensor and the Ricci tensor of (∈)-Lorentzian para-Sasakian manifold are investigated. Further, we study globally φ-Ricci symmetric and weakly φ-Ricci symmetric (∈)-Lorentzian para-Sasakian manifolds and obtain interesting results. [ABSTRACT FROM AUTHOR]
