Abstract: 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 that a conformally flat generalized Ricci-recurrent spacetime with certain… read more here.

Abstract: In this paper, we introduce and investigate a novel space-time, named a pseudo generalized Z-recurrent spacetime. Next, we illustrate that a pseudo generalized Z-recurrent spacetime with Codazzi type of Ricci tensor is a pseudo quasi-Einstein… read more here.
