On the basis of the general relativistic statistical and kinetic theory, a consistent closed cosmological model is formulated. It is based on a statistical system of scalar charged fermions interacting by means of classical and phantom scalar fields.

A complete cosmological evolution model of the classical scalar field with a Higgs potential is studied and simulated on a computer without the assumption that the Hubble constant is nonnegative. It is shown that with most initial conditions, the cos

Using a self-consistent field, we construct a complete theory of the macroscopic description of cosmological evolution, including a subsystem of linear equations for the evolution of perturbations and nonlinear macroscopic Einstein equations and a sc

Free oscillations of scalar fields with a Higgs potential are investigated in cosmological models based on scalar fields, both in the case of isolated classical and phantom fields and in the case of an asymmetric scalar doublet. On the basis of numer

The revision of the Author's results with respect to possibility of existence of the so-called Euclidian cycles in cosmological evolution of a system of Higgs scalar fields has been performed. The assumption of non-negativity of the Universe's extens

Based on study of partial melting in the model pyrolite, it is shown that garnets synthesized at 7.0 GPa in a temperature range of 1400–1800°C are characterized by an excessive Si content (in relation to 3 f.u.), stable admixture of Cr2O3, and, th
