The open Universe model as an oscillatory task in a homogenous force field

Baranov A. M., Saveljev E. V.

The possibility of finding the exact cosmological solutions of the Einstein equations without cosmological constant for open model of the Universe is considered within the framework of an equivalent oscillatory task in a homogeneous force field (“a mechanical approach”). The taken cosmological model is filled with the matter in approach of perfect fluid with a pressure not equal to zero. On the asymptotic infinity this model is the open cosmological model of Friedman. The influence of the "force field"on behavior of model is discovered. The evolution of the expansion of the open massless Universe complete model from the vacuum state of relativistic strings to the ultra-relativistic regime has also been obtained.
