Generation of limit cycles from separatrix polygons in the phase plane, which are saddle points and the sides of which are separatrices connecting these saddle points. They are structurally unstable, and in this paper we will study the change in the phase portrait due to arbitrary small changes in the right hand sides of these systems. In particular, attention will be

Periodic solutions of continuous self-gravitating systems,riate Poisson-equation. Such a system can be studied by associating it with dynamical systems in a finite-dimensional phase-space. The finite-dimensional problems are treated in the frame-work of KAM-theory by Birkhoff normalization and averaging techniques. This leads to a classification of possibl
