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…

Characterizations of a Lorentzian Manifold with a semi-symmetric metric connection
Uday Chand De, Krishnendu De, Sinem Güler
In this article, we characterize a Lorentzian manifold with a semi-symmetric metric connection. At first, we consider a semi-symmetric metric connection whose curvatu…
