Energy conditions and modified gravity in anisotropic universe

2018 
‎‎In this paper‎, ‎energy conditions in a new f (G, T) modified gravity (G and T represent the Gauss-Bonnet invariant and trace of‎ the energy-momentum tensor‎, ‎respectively) for anisotropic universe with perfect fluid are analyzed‎. In this model‎, ‎we develop the general scheme for new f (G, ‎T) modified gravity reconstruction from realistic anisotropic Bianchi type I‎ cosmology‎. ‎Using de Sitter solution‎, ‎the exact solutions of the field equations has been obtained‎. It is found that null and weak energy conditions are satisfied for the parameter range considered‎. As a result‎, ‎the analysis show that the increase of anisotropy is attributed to the increase of weak energy condition.
