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.

Comparison of energy conditions in general relativity and modified theories of gravity
International Journal of Geometric Methods in Modern Physics, 2023To 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])
