Title: Resonant tori of arbitrary codimension for quasi-periodically 
forced systems

Abstract:
I will discuss the problem of persistence of lower-dimensional tori for 
nearly
integrable Hamiltonian systems. I will show that for a system of rotators
subject to a small quasi-periodic forcing there exists at least one 
quasi-periodic
solution with the same frequency as the forcing, assuming time-reversibility
on the perturbation (instead of a non-degeneracy condition as in the
literature). The result is obtained in collaboration with G. Gentile.
