    Abstract:

    The study of slightly modificated Friedmann-Robertson-Walker cosmological models is considered by introducing inhomogeneities into them. The cosmologies in this case are filled with two cosmic fluids: one with homogeneous and isotropic properties and another inhomogeneous and anisotropic. It is shown that the dynamics of the scale factor of these inhomogeneous cosmological models are governed by the standard Friedmann equations.
