Einstein like -para Sasakian manifolds
Kuwait Journal of Science, 2013 Einstein like -para Sasakian manifolds are introduced. For an -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.

On Ricci solitons in LP-Sasakian manifolds
Bibechana, 2020 In this paper we study Ricci solitons in Lorentzian para-Sasakian manifolds. It is proved that the Ricci soliton in a (2n+1)-dimensinal LP-Sasakian manifold is shrinking.

Curvature Properties of Quasi-Para-Sasakian Manifolds
International Electronic Journal of Geometry, 2019 The paper is devoted to study quasi-para-Sasakian manifolds. Basic properties of such manifolds are obtained and general curvature identities are investigated. Next it is proved that if M is a quasi-para-Sasakian manifold of constant curvature K. Then K

On $(epsilon)$ - Lorentzian para-Sasakian Manifolds
Iranian Journal of Mathematical Sciences and Informatics, 2022 Summary: The object of this paper is to study \((\epsilon)\)-Lorentzian para-Sasakian manifolds. Some typical identities for the curvature tensor and the Ricci tensor of \((\epsilon)\)-Lorentzian para-Sasakian manifold are investigated. Further, we study globally \(\phi\)-Ricci symmetric and weakly \(\phi\)-Ricci symmetric \((\epsilon)\)-Lorentzian ...
