Аннотация: The derivation of exact cosmological solutions describing an open universe with a conformally flat metric and volume viscosity is discussed. The method used in the article permits the modeling of an open universe to be reduced to the problem of mechanical motion of a particle in a specified force field. The behavior of the equationПоказать полностьюof state, which changes as the universe evolves, is investigated. A new exact solution of the gravitation equations is found in a simple form corresponding to an equivalent, variable-frequency oscillator with linear damping.
