de Sitter initial state of the universe as a result of the asymptotic disappearance of gravitational interactions of matter
Markov M. A. , Mukhanov V. F.
In the "effective" action for the gravitational field and matter, the "constant" of the coupling of the matter with gravitation is a function of the energy density. In this case а Л-shaped term automatically arises in the Einstein equations. The particular conditions under which the initial state of the universe turns out to be a de Sitter state are analyzed.
