Impact of m-projective curvature tensor in f (, G)-gravity and f (,  m )-gravity

This article deals with the characterization of a spacetime and modified gravity, such as f  , G -gravity and f  ,  m -gravity endowed with the m -projective curvature tensor. At first, we show that a m -projectively flat perfect fluid spacetime satisfying Einstein’s field equations represents a...
