Accelerating & Decelerating Higher-Dimensional Plane Symmetric Cosmological Models with Perfect Fluid & Dark Energy

Abstract

We have studied the Plane Symmetric cosmological models with a binary mixture of perfect fluid and dark energy in higher dimensions. The perfect fluid is obeying the equation of state p=γρ with γ ɛ[0, 1] ,whereas, the dark energy is considered to be either the quintessence or the Chaplygin gas. The exact solutions of Einstein’s field equations corresponding to five dimensions are obtained. Models with power-law and exponential expansion have discussed in detail.
