A KAM algorithm for the resonant non--linear Schrödinger equation
Abstract
In this note we use the normal forms of the completely resonant non--linear Schrödinger equation on a torus (NLS) derived in previous work in order to produce, under a KAM algorithm, large families of stable and unstable quasi periodic solutions for the NLS in any number of independent frequencies.
