The Averaging Principle. Fluctuations in Dynamical Systems with Averaging,In Chap.?7, rapidly oscillating stochastic perturbations of dynamical systems are considered. Results of the law-of-large-numbers type, those of central-limit theorem type, and large-deviation results are obtained. Those last results are applied to the asymptotics of the behavior of the perturbed dynamical system on growing time intervals.

The Multidimensional Case,low motion. If the non-perturbed system has no saddle-type points, we can, in the one-degree-of-freedom case, characterize the slow motion by the value of the Hamiltonian (in the multidimensional case with several first integrals, by the values of those first integrals). If there are saddle-type poi
