A spacetime with pseudo-projective curvature tensor

Journal of Mathematical Physics, 2016
The object of the present paper is to study spacetimes admitting pseudo-projective curvature tensor. At first we prove that a pseudo-projectively flat spacetime is Einstein and hence it is of constant curvature and the energy momentum tensor of such a spacetime satisfying Einstein’s field equation with cosmological constant is covariant constant.

Impact of pseudo-projective curvature tensor on a space-time and f(r,G)-gravity

International Journal of Geometric Methods in Modern Physics
In this paper, we classify pseudo-projectively flat space-times and acquire that it represents either a de Sitter space-time or an anti-de Sitter space-time. Furthermore, we obtain that a pseudo-projectively flat perfect fluid space-time represents dark matter era and Robertson–Walker space-time.
