ABSTRACT

The problem of the study of N-body gravitating systems is considered from the point of view of the relevance of the computer-created model with the physical one. It is shown that due to the discontinuity of the Lyapunov characteristic exponents their numerical calculations cannot be a proper method of studying the instability properties of the system. This fact occurs both for systems with softened (independent on the way of softening) and, what is more interesting, even for unsoftened (i.e., pure Newtonian) potential. More... »
