General relativistic analogies of the isotropic models and limitations on observable quantities in the scalar-tensor cosmology

In the scalar-tensor cosmology analytical solutions have been found for isotropic models with a curvature. Relations between metagalaxy parameters observed are discussed and restrictions on the velocity of variation of the constant of mass gravitation interaction are refined. It has been shown that the scalar field can dominate even in the present epoch, and its energy contribution comparable with the critical density is quite allowable
