Spherically symmetric cosmological perturbations in flat space-time theory of gravitation

The previously developed equations for the propagation of perturbations in a homogeneous, isotropic cosmological model are studied. At the beginning of the universe spherically symmetric inhomogeneities can arise. In the dust dominated universe the growth of spherically symmetric perturbations is given in form of infinite series. The increase of the inhomogeneity is faster than in general relativity.
