course: Averaging principle and long time behavior of weakly coupled oscillators
speaker: Mark Freidlin (Department of Mathematics, Univ.of Maryland, College Park, MD 20742)abstract: I will consider small perturbations of a simple completely integrable system with many degrees of freedom: a collection of independent one-degree of freedom oscillators (in the perturbed system the individual oscillators are no longer independent). It turns out that the long time behavior of such a system, even in the case of pure deterministic perturbations, should, in general, be described as a stochastic process. The limiting stochastic process is a Markov process on an open book space corresponding to the collection of first integrals of the non-perturbed system.
