| Аннотация |
On the basis of qualitative theory of differential equations it is shown that dynamic system based on the system of Einstein - Klein - Gordon equations with regard to Friedman Universe has a stable center
corresponding to zero values of scalar potential and its derivative at infinity. Thus, the cosmological model based on single massive classical scalar field in infinite future would give a flat Universe. The carried out numerical simulation of the dynamic system corresponding to the system of Einstein - Klein - Gordon equations showed that at great times of the evolution the invariant cosmological acceleration has a microscopic oscillating character (T 2mt), while macroscopic value of the cosmological acceleration varies from +1 at inflation stage after which if decreases fast to −1/2 (non-relativistic stage), and then slowly tends to −1 (ultrarelativistic stage).
