Finite dimensional invariant KAM tori for tame vector fields
Livia Corsi, Roberto Feola, Michela Procesi
We discuss a Nash-Moser/ KAM algorithm for the construction of invariant tori for {\em tame} vector fields. Similar algorithms have been studied widely both in finite and infinite…

KAM for quasi-linear forced hamiltonian NLS
Roberto Feola
In this paper we prove the existence of quasi-periodic, small-amplitude, solutions for quasi-linear Hamiltonian perturbations of the non-linear Schroedinger equation on the torus i…
