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.

Some Classes of Pseudosymmetric Contact Metric 3‐Manifolds

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
We study (a) the class of 3‐dimensional pseudosymmetric contact metric manifolds with harmonic curvature and Trl constant along the direction of ξ and (b) the class of (κ, μ, ν)‐contact metric pseudosymmetric 3‐manifolds of type constant in the direction of ξ.

η-RICCI SOLITONS IN (ϵ,δ)-TRANS SASAKIAN MANIFOLDS [PDF]

open access: yes, 2019
The object of the present research is to study the (ϵ,δ)-TransSasakian manifolds addmitting the η-Ricci Solitons. It is shown that a sym-metric second order covariant tensor in an (ϵ,δ)-Trans Sasakian manifold isa constant multiple of metric tensor. Also

On the Conharmonic Curvature Tensor of Generalized Sasakian‐Space‐Forms

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
The object of the present paper is to characterize generalized Sasakian‐space‐forms satisfying certain curvature conditions on conharmonic curvature tensor. In this paper we study conharmonically semisymmetric, conharmonically flat, ξ‐conharmonically flat, and conharmonically recurrent generalized Sasakian‐space‐forms.

Chen optimal inequalities of CR-warped products of generalized Sasakian space form

open access: yesJournal of Taibah University for Science, 2020
Our main objective of this paper is to derive the relationship between the main extrinsic invariant, and the contact CR δ-invariant (new intrinsic invariant) on a generic submanifold in trans-Sasakian generalized Sasakian space forms.

Special Trans-Sasakian Manifolds and Curvature Conditions [PDF]

open access: yes, 2012
In this paper a special type of trans-Sasakian manifolds called -trans-Sasakian manifolds are studied. We present some general results for sectional curvatures of higher dimensional -trans-Sasakian manifolds and establish relations among the sectional ...

Ricci Solitons in (ϵ)-Trans-Sasakian Manifolds

open access: yesJournal of the Tensor Society, 2007
We study Ricci solitons in (ϵ)-trans-Sasakian manifolds. It is shown that a symmetric parallel second order covariant tensor in a (ϵ)-trans-Sasakian manifold is a constant multiple of the metric tensor. Using this it is shown that if LV g + 2S is parallel where V is a given vector field, then (g, V ) is Ricci soliton. Further, by virtue of this result,
