We present recent existence results for small amplitude periodic and quasi-periodic solutions of completely resonant nonlinear wave equations. Both infinite-dimensional bifurcation phenomena and small divisors difficulties occur. The proofs rely on the bifurcation theory, the Nash-Moser implicit function theorem, dynamical systems techniques and variational methods.

Abstract
We present recent existence results for small amplitude periodic and quasi-periodic solutions of completely resonant nonlinear wave equations. Both infinite-dimensional bifurcation phenomena and small divisors difficulties occur. The proofs rely on the bifurcation theory, the Nash-Moser implicit function theorem, dynamical systems techniques and variational methods.File in questo prodotto:
