Comparison of energy conditions in general relativity and modified theories of gravity

International Journal of Geometric Methods in Modern Physics, 2023
To make a comparison of energy conditions in the theory of general relativity and in the modified theories, we have considered [Formula: see text], [Formula: see text] and [Formula: see text] theories (where [Formula: see text] and [Formula: see text] are the Ricci scalar and trace of the energy–momentum tensor, respectively, while [Formula: see text])

Energy conditions and modified gravity in anisotropic universe

Canadian Journal of Physics, 2018
In this paper, energy conditions in a new [Formula: see text] modified gravity ([Formula: see text] and T represent the Gauss–Bonnet invariant and trace of the energy–momentum tensor, respectively) for anisotropic universe with perfect fluid are analyzed.
