Query: First numerical evidence of global Arnold diffusion in quasi--integrable
  systems   We provide numerical evidence of global diffusion occurring in slightly
perturbed integrable Hamiltonian systems and symplectic maps. We show that even
if a system is sufficiently close to be integrable, global diffusion occurs on
a set with peculiar topology, the so--called Arnold web, and is qualitatively
different from Chirikov diffusion, occurring in more perturbed systems.
