	abstract = {We present, in the context of nearly integrable Hamiltonian systems, a functional analysis
approach to study the {\textquotedblleft}splitting of the whiskers{\textquotedblright} and the {\textquotedblleft}shadowing problem{\textquotedblright} developed
in collaboration with P. Bolle in the recent papers [1] and [2] . This method is applied to the
problem of Arnold diffusion for nearly integrable partially isochronous systems improving
known results.},
