CENTRO DI RICERCA MATEMATICA ENNIO DE GIORGI

Nell'ambito del semestre su "Analisi Stocastica", Mercoledi' 31 Maggio, alle 10.30, MARK FREIDLIN (University of Maryland) terra' una lezione dal titolo:

"Averaging principle and long time behavior of weakly coupled oscillators"

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.

La lezione si terra' nella Sala Conferenze del Collegio Puteano.
