Moser’s C-version of Kolmogorov’s theorem on the persistence of maximal quasi-periodic solutions for nearly-integrable Hamiltonian system is extended to the persistence of non-maximal quasi-periodic solutions corresponding to lower-dimensional elliptic tori of any dimension n between one and the number of degrees of freedom. The theorem is proved for Hamiltonian functions of class C for any >6n + 5 and the quasi-periodic solutions are proved to be of class Cp for any p with 2<p<p∗ for a suitable p∗ = p∗(n, )>2 (which tends to infinity when →∞).

Abstract

Moser’s C-version of Kolmogorov’s theorem on the persistence of maximal quasi-periodic solutions for nearly-integrable Hamiltonian system is extended to the persistence of non-maximal quasi-periodic solutions corresponding to lower-dimensional elliptic tori of any dimension n between one and the number of degrees of freedom. The theorem is proved for Hamiltonian functions of class C for any >6n + 5 and the quasi-periodic solutions are proved to be of class Cp for any p with 22 (which tends to infinity when →∞).
