Dynamical systems

in nearly integrable Hamiltonian systems the action variables drift only over times exponentially long in the inverse size of the perturbation.

In dynamical systems, Nekhoroshev theorem refers to in nearly integrable Hamiltonian systems the action variables drift only over times exponentially long in the inverse size of the perturbation. This meaning comes from Nekhoroshev (1977) in Russian Mathematical Surveys.[1]
