Vm. Zhuravlev et Sv. Chervon, Cosmological inflation models admitting natural emergence to the radiation-dominated stage and the matter domination era, J EXP TH PH, 91(2), 2000, pp. 227-238
A model of the evolution of the uniform and isotropic spatially-flat univer
se, where the inflation stage emerges naturally into the radiation-dominate
d stage and the matter-dominated era, is proposed on the basis of exact sol
utions of the self-consistent equations of a gravitating self-acting scalar
field. It is shown that the model contains two basic physical mechanisms,
one of which is related with the decay of Higgs bosons and provides for the
inflation stage, while the second mechanism is associated with the adiabat
ic expansion of the universe filled with matter with a definite equation of
state and gives a Friedmann expansion regime. (C) 2000 MAIK "Nauka/Interpe
