On semi-Quasi-Einstein Manifold
Yanling Han, Avik De, Peibiao Zhao
In the present paper we introduce a semi-quasi-Einstein manifold from a semi symmetric metric connection. Among others, the popular Schwarzschild and Kottler spacetimes are shown t…
Almost pseudo-Ricci symmetric spacetime solutions in -gravity
Avik De, Loo-Tee How
The objective of the present paper is to study 4-dimensional almost pseudo Ricci symmetric perfect fluid spacetimes . We show that a Robertson-Walker spacetime is $(APRS)…
Energy conditions for a spacetime in -gravity
Avik De, Tee-How Loo, Simran Arora +1
The objective of the present paper is to study 4-dimensional weakly Ricci symmetric spacetimes with non-zero constant Ricci scalar. We prove that such a satisfy…
A Conformally Flat Generalized Ricci Recurrent Spacetime in F(R)-Gravity
Avik De, Tee-How Loo, Raja Solanki +1
In the present paper we study a conformally flat generalized Ricci recurrent perfect fluid spacetime with constant Ricci scalar as a solution of modified -gravity theory. We…
