Abstract
We introduce an integrable isochronous system and perturb its frequenc y by an external-deterministic or purely random-noise. Under the pertu rbation the action variable evolves in time: the corresponding diffusi on coefficient is exactly computed and its dependence on the magnitude of the perturbation is carefully investigated. Different behaviors ar e found and justified: the quasilinear approximation, the superlinear regime, and the ballistic motion.
