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

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 ) = f 1 ( R ) + f 2 ( R ) corresponding to stiff fluid, is obtained. Physical and kinematical properties of the model are also studied.
