Using the self-consistent field method, a complete theory of a macroscopic description of cosmological evolution is constructed, which includes a subsystem of linear equations of evolution of perturbations and nonlinear macroscopic equations of Einstein and a scalar field. Examples of the solution of this system are presented, illustrating the fundamental difference between the cosmological models of the early Universe built on homogeneous and locally fluctuating scalar fields. Corrections to the equation of state of the fluid are found,
based on the macroscopic Einstein equations which were obtained by averaging over microscopic
spherically symmetric metric fluctuations created by primordial black holes in a fluid medium.
It is shown that these corrections are effectively equivalent to addition to the system of a fluid
with the equation of state $p=-\varepsilon$. |
