Abstract


We study a particular perturbation of the Kepler problem givenby the potential U(r, ?) = ?1/r ? b/r2(1 + cos2 ?), where b and are theperturbation parameters. This problem has two first integrals in involution:the first one is the well known Hamiltonian H = (p2r+p2?/r2)?1/r?b/r2(1+ cos2 ?); the second one is given by G = p2?/2 ? b/(1 + cos2 ?). The setsH?1(h), G?1(g) and H?1(h)G?1(g) are invariant under the flow of theHamiltonian system. From here we obtain a nice foliation of the phase space.In this paper we study the topology of the above foliation.
