KAM for quasi-linear KdV

We prove the existence and the stability of Cantor families of quasi-periodic, small amplitude, solutions of quasi-linear autonomous Hamiltonian and reversible KdV equations. The proof is based on a Nash-Moser scheme, the search of an approximate inverse for the linearized operators, a KAM reducibility scheme and a Birkhoff normal form argument.
