We study strongly non-stationary stochastic processes which take place in the phase space of disk-like self-gravitating systems at the early stage of their evolution. Numerical calculations were carried out based on the model of chaotic effects according to which the selected phase volume is experienced by random pushes that have diverse and complicated character.

In this paper, we study the strong non-stationary stochastic processes that take place in the phase space of self-gravitating systems at the earlier non-stationary stage of their evolution. The numerical calculations of the compulsive phase mixing process were carried out according to the model of chaotic impacts, where the initially selected phase volume experiences random pushes that are of a diverse and complex nature. The application of the method for studying random impacts on a volume element in the case of three-dimensional space is carried out.
