Energy conditions for a (WRS)(4) spacetime in F(R)-gravity
The objective of the present paper is to study four-dimensional weakly Ricci symmetric spacetimes (WRS)(4) with nonzero constant Ricci scalar. We prove that such a (WRS)(4) satisfying F(R)-gravity field equations represents a perfect fluid with vanishing vorticity. Some energy conditions are studied...
