Akad. Nauk Ukraïni3 aWe present, in the context of nearly integrable Hamiltonian systems, a functional analysis
approach to study the “splitting of the whiskers” and the “shadowing problem” 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.1 aBerti, Massimiliano  uhttps://math.sissa.it/publication/arnold-diffusion-functional-analysis-approach
