On Pseudo -symmetric spacetimes and gravity
Young Jin Suh, Krishnendu De, Uday Chand De
This article delivers the characterization of a pseudo symmetric spacetimes and we illustrate that a pseudo symmetric spacetime admitting Codazzi type of -tensor represe…
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.
Sufficient conditions for a pseudosymmetric spacetime to be a perfect fluid spacetime
Peibiao Zhao, Uday Chand De, Bülent Ünal +1
The aim of the present paper is to obtain the condition under which a pseudosymmetric spacetime to be a perfect fluid spacetime. It is proven that a pseudosymmetric generalized Rob…
Perfect fluid spacetimes and gradient solitons
Krishnendu De Uday Chand De, Abdallah Abdelhameed Syied, Nasser Bin Turki +1
This article deals with the investigation of perfect fluid spacetimes endowed with concircular vector field. It is shown that in a perfect fluid spacetime with concircular vector f…
