Spatially homogeneous bianchi type-i perfect fluid cosmological models in f(R) gravity theory

Abstract

In this paper we have investigated a spatially homogeneous and anisotropic Bianchi type I model filled with perfect fluid in f(R) gravity theory. Exact solutions of the field equations are obtained by considering specific ansatz of the average scale factor, which correspond to accelerating models of the universe. The physical and kinematical features of the cosmological models are discussed. © Electronic Journal of Theoretical Physics.
