Characterization of generalized quasi-Einstein manifolds and modified gravity
Uday Chand De, Hülya Bağdatli Yilmaz
In this work, a detailed examination of a specific case of a generalized quasi-Einstein manifold (GQE)n is provided. It begins by exploring generalized quasi-Einstein spacetimes un…
Pseudo generalized Ricci-recurrent spacetimes and modified gravity
Krishnendu De, Uday Chand De
In this paper we introduce and characterize a pseudo generalized Ricci-recurrent spacetimes and produce an example to verify the existence of such a spacetime. Then we demonstrate…
Pseudo generalized Ricci-recurrent spacetimes with certain applications to modified gravity
Uday Chand De, Krishnendu De
In this article we introduce and characterize a pseudo generalized Ricci-recurrent spacetimes. At first, we produce an example to justify the existence of such a spacetime. Then, i…
Impact of projective curvature tensor in , and -gravity
Young Jin Suh, Krishnendu De, Uday Chand De
This article concerns with the characterization of a spacetime and modified gravity, such as , and -gravity equipped w…
Some curvature properties of perfect fluid spacetimes
Krishnendu De, Uday Chand De, Ljubica Velimirovic
In this paper we assume that a perfect fluid is the source of the gravitational field while analyzing the solutions to the Einstein field equations.
A complete study of conformally flat pseudo-symmetric spacetimes in the theory of F(R)-gravity
Avik De, Simran Arora, Uday Chand De +1
We investigate the geometrical and physical structures of a pseudo-symmetric spacetime with timelike vector under the condition of conformal flatness. We classify it into…
