Abstract

We have presented exact solutions of Einstein field equations for a hypersurface-homogeneous space time in the presence of a perfect fluid with constant EoS parameter. One solution corresponds to a cosmological model filled with stiff matter which may be useful for the description of the early stages of the universe. The other two solutions represent recent accelerating expanding models filled with dark energy and negative EoS parameter. The physical and kinematical properties of the models are discussed.
