“…Thus, for instance, the classical solution of S. Kovalevskaya [7] of the problem of a heavy rigid body's movement was found on the way to finding single valued solutions. A systematic investigation of singular points of solutions together with a compactification of the flow, defined by the Euler-Poisson equations [8], allow not only to find partial entire and finite valued solutions with some specified properties of their singular points, but also to study global properties of infinite valued solutions [9]. In this case applying the same approach to another problem of classical mechanics, particularly-the three body problem, seems to be quite natural.…”
