Almost pseudo-Ricci symmetric spacetime solutions in F(R)-gravity
The objective of the present paper is to study 4-dimensional almost pseudo Ricci symmetric perfect fluid spacetimes ( APRS ) 4 . We show that a Robertson–Walker spacetime is ( APRS ) 4 and vice versa under certain condition imposed on its scale factor. Some popular toy models of F ( R )-gravity are...
