A Study on Ricci Solitons in Kenmotsu Manifolds

open access: yesInternational Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
We study and obtain results on Ricci solitons in Kenmotsu manifolds satisfying R(ξ, X) · B = 0, B(ξ, X) · S = 0, S(ξ, X) · R = 0, R(ξ,X)·P¯=0, and P¯(ξ,X)·S=0, where B and P¯ are C‐Bochner and pseudo‐projective curvature tensor.

CHARACTERIZATION OF $\phi$-SYMMETRIC LORENTZIAN PARA-KENMOTSU MANIFOLDS [PDF]

open access: yes, 2023
The purpose of the present paper is to explore the characteristics of the Lorentzian $\phi$-symmetric para-Kenmotsu manifold as an Einstein manifold. In this paper, we also study the parallel 2-form on the LP-Kenmotsu manifold (LP-Kenmotsu manifold is ...

Harmonic (p, q)‐Curves in Trans‐Sasakian and Normal Almost Paracontact Metric Manifolds

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we give some characterizations about biharmonic, f‐harmonic, and f‐biharmonic (p, q)‐curves in 3‐dimensional trans‐Sasakian and normal almost paracontact metric manifolds. The (p, q)‐curves are considered as generalizations of magnetic curves.

Geometric Classifications of Perfect Fluid Space‐Time Admit Conformal Ricci‐Bourguignon Solitons

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
This paper is dedicated to the study of the geometric composition of a perfect fluid space‐time with a conformal Ricci‐Bourguignon soliton, which is the extended version of the soliton to the Ricci‐Bourguignon flow. Here, we have delineated the conditions for conformal Ricci‐Bourguignon soliton to be expanding, steady, or shrinking.

η-Ricci solitons on Lorentzian para-Sasakian manifolds

open access: yesFilomat, 2016
We consider η-Ricci solitons on Lorentzian para-Sasakian manifolds satisfying certain curvature conditions: R(ξ,X) · S = 0 and S · R(ξ,X) = 0. We prove that on a Lorentzian para-Sasakian manifold (M, φ, ξ, η, 1), if the Ricci curvature satisfies one of the previous conditions, the existence of η-Ricci solitons implies that (M, 1) is Einstein manifold ...

Quasi Conformal Curvature Tensor on a Lorentzian Para-Sasakian Manifold

open access: yesJournal of the Tensor Society, 2009
In This paper, we consider quasi-conformally flat, quasi-conformally conservative and -quasi conformally flat Lorentzian para-sasakian manifold. It has also been proved that an Einstein Lorentzian para-sasakian manifold satisfying the relation R(X, Y). = 0, where is a quasi-conformal curvature tensor is locally isometric with a unit sphere.
