On lightlike geometry of para-Sasakian manifolds. [PDF]
ScientificWorldJournal, 2014 We study lightlike hypersurfaces of para-Sasakian manifolds tangent to the characteristic vector field. In particular, we define invariant lightlike hypersurfaces and screen semi-invariant lightlike hypersurfaces, respectively, and give examples ...

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.

ON (ϵ)-LORENTZIAN PARA-SASAKIAN MANIFOLDS
Communications of the Korean Mathematical Society, 2012 In this paper we study (ϵ)-Lorentzian para-Sasakian mani- folds and show its existence by an example. Some basic results regarding such manifolds have been deduced. Finally, we study conformally at and Weyl-semisymmetric (ϵ)-Lorentzian para-Sasakian manifolds.

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 the geometry of warped product submanifolds of a quasi-hemi Slant submanifold with trans para Sasakian [PDF]
Journal of Hyperstructures, 2023 The existence or non-existence of warped product quasi-hemi slant submanifolds in trans para-sasakian manifolds is defined. Then we obtain that there are no proper warped product quasi-hemi slant submanifolds in trans para-sasakian manifolds such that ...

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 ...

Metallic structures on tangent bundles of Lorentzian para-Sasakian manifolds [PDF]
Journal of Mahani Mathematical Research, 2023 Let M be a Lorentzian para-Sasakian manifold with a Lorentzian para-Sasakian structure (φ,η,ξ,g). In this paper, we introduce some metallic structures on tangent bundle of the manifold M using vertical, horizontal and complete lifts of the Lorentzian ...
