On a method for the analysis of compulsive phase mixing and its
  application in cosmogony of galaxy superclusters
  In this paper, we study the strong non-stationary stochastic processes that
take place in the phase space of self-gravitating systems at the initial
non-stationary stage of their evolution. The numerical calculations of the
compulsive phase mixing process were carried out based on the model of chaotic
impacts, according to which the initially selected phase volume experiences
random impacts of a different and complex nature.
