ABOUT PRESSURE IN MODEL OF THE EXPANDING UNIVERSE

Closed model of Universe on the earlier stage of its evolution is defined more precisely. It is considered here that after the Big Bang and De Sitter’s (exponential) expanding phase in which the pressure is (see [1-3]) the post De Sitter’s stage is beginning. State equation on this stage is written in the form , where is some pure geometrical factor. Here this equation is investigated and boundary conditions for it are formulated. Explicit expression for in the class of almost periodical functions is found, that permits to integrate the conservation law. Outgoing from this we come to the following conclusion: at the post De-Sitter’s stage the configuration space of Universe is the Bohr’s compact. Manifold R on which acceleration is positive are found. Due to the vibrant character of depending this manifold may advance far in future that is compatible with observed data. c c p ρ 2 − =
