The problem of stability for the homogeneous and isotropic Universe in RTG

The question of stability of homogeneous and isotropic Universe relative to small fluctuations of gravitational field and matter characteristics has been investigated in the framework of RTG. The equations for small perturbations of metric tensor gμν, energy density ρ and pressure p are obtained in linear approximation. The solutions of these equations are found provided the perturbations depending on time only. The analysis of physical nature of derived solutions is carried out. The comparison with the results of GR leads to the conclusion that all the distinctions are caused by the mass of graviton
