文摘

We have studied anisotropic behavior of the universe through LRS Bianchi type-I model in the context of f(R,Tψ)f(R,Tψ) gravity. We evaluate H  , ωeffωeff and V(ψ)V(ψ) through the first order formalism for scalar fields. We have investigated the behavior of these parameters for different values of W(ψ)W(ψ). We conclude that exponential model of W(ψ)W(ψ) can explain the evolution of Bianchi type-I universe as compared to other models.
