Bianchi Type-I Universe with Cosmological Constant and Quadratic Equation of State in f (R, T) Modified Gravity

摘要

This paper deals with the study of Bianchi type-I universe in the context of f(R,T) gravity. Einstein's field equations in f(R,T) gravity have been solved in the presence of cosmological constant. and quadratic equation of state (EoS) p = alpha rho(2) - rho, where alpha not equal 0 is a constant. Here, we have discussed two classes of f(R,T) gravity; that is, f(R,T) - R + 2f (T) and f(R,T) - f(1) (R) + f(2) (T). A set of models has been taken into consideration based on the plausible relation. Also, we have studied some physical and kinematical properties of the models.
