On the Conharmonic Curvature Tensor of Generalized Sasakian-Space-Forms [PDF]
ISRN Geometry, 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, -conharmonically flat, and conharmonically recurrent generalized Sasakian-space-forms.

LP-Sasakian Manifolds Equipped with Zamkovoy Connection and Conharmonic Curvature Tensor [PDF]
Journal of the Indonesian Mathematical Society, 2021 In this paper we have proved some results on conharmonically flat, quasi conharmonically flat and φ-conharmonically flat LP-Sasakian manifolds with respect to Zamkovoy connection. Also, we study generalized conharmonic φ-recurrent LP-Sasakian manifolds with respect to Zamkovoy connection. Moreover, we study LP-Sasakian manifolds satisfying K*(ξ,U)∘R*=0,

LP‐Kenmotsu Manifolds Admitting η‐Ricci Solitons and Spacetime
Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 In the present paper, LP‐Kenmotsu manifolds admitting η‐Ricci solitons have been studied. Moreover, some results for η‐Ricci solitons in LP‐Kenmotsu manifolds in the spacetime of general relativity have also been proved. Through a nontrivial example, we have given a proof for the existence of η‐Ricci solitons in a 5‐dimensional LP‐Kenmotsu manifold.

Imperfect Fluid Generalized Robertson Walker Spacetime Admitting Ricci‐Yamabe Metric
Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021 In the present paper, we investigate the nature of Ricci‐Yamabe soliton on an imperfect fluid generalized Robertson‐Walker spacetime with a torse‐forming vector field ξ. Furthermore, if the potential vector field ξ of the Ricci‐Yamabe soliton is of the gradient type, the Laplace‐Poisson equation is derived.

A Study of Generalized Projective P−Curvature Tensor on Warped Product Manifolds
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 The main aim of this study is to investigate the effects of the P−curvature flatness, P−divergence‐free characteristic, and P−symmetry of a warped product manifold on its base and fiber (factor) manifolds. It is proved that the base and the fiber manifolds of the P−curvature flat warped manifold are Einstein manifold.

Optimization on Conharmonic and Conformal Curvature tensors in Einstein Field equations
, 2023 Abstract Ahsan (2005) has studied the geometrical symmetry of spacetime of general relativity. Also, Blair et. al. (2005) has premeditated concircular curvature tensor of a contact metric manifold. After that, Negi and Su-lochana (2021) calculated the conformal Symmetric Tensor of Kaehlerian Manifolds.
