                                            Abstract

We revisit some results of perturbation theories by a method of successive elimination of harmonics inspired by some ideas of
Delaunay. On the one hand, we give a connection between the KAM theorem and the Nekhoroshev theorem. On the other hand, we
support in a quantitative fashion a semi-numerical method of analysis of a perturbed system recently introduced by one of the
authors.
