Five-Dimensional Stiff Fluid Cosmological Model in f(R,T) Gravity with /\(t)

Abstract

Five dimensional Kaluza-Klein spacetime is considered in a modified theory of gravitation proposed by Harko et al. (Phys. Rev. D 84: 024020, 2011) which is known as f(R,T) gravity in the presence of perfect fluid distribution. Cosmological model for a specific choice of f(R,T) = f₁(R) + f₂(R) corresponding to stiff fluid, is obtained. Physical and kinematical properties of the model are also studied.
