Five - Dimensional Plane Symmetric Cosmological Model with Quadratic Equation of State in f(R,T) Theory of Gravity

Abstract

In this paper, we analysed the five-dimensional plane-symmetric cosmological model containing perfect fluid in the context of f(R, T) gravity. Field equations have solved for two class of f(R, T) gravity i.e., f(R, T) = R + f(T) and f(R, T) = f1(R)f2(T) with the inclusion of cosmological constant Λ and quadratic equation of state parameters in the form p = αρ2 − ρ, where α is a constant and strictly α≠ 0. In order to derive the exact solutions, we utilize volumetric power law and exponential law of expansion. The physical and geometrical aspects of model have discussed.
