Description
Integrable systems become chaotic as soon as one perturbs
them with an external, additive random noise. The Lyapunov
exponents are a power law of the noise intensity. The
regime being by nature beyond the Kolmogorov Arnold Moser (and
also the Nekhoroshev) regimes, it offers us a glimpse of the
behavior of weakly chaotic deterministic systems, in an
multi-resonance situation.
