    • When the nonlinearity of the system is large, equipartition of energy is intended in its generalized form: see, e.g., A. Münster, Statistical Thermodynamics (Springer-Verlag, Berlin, 1969), Vol. 1.

    • When the anharmonicity in the system is large, one should define the weights on the basis of the generalized equipartition theorem; for a discussion of this point see Ref. [16].

    • note
    • The Poincaré-Fermi nonexistence theorem states that for a number N of degrees of freedom ≥ 3, no analytic or smooth integral of motion besides the energy exists for nonintegrable systems. Thus, the nonintegrable motions (those that do not live on KAM tori) belong to a connected component of phase space and the whole of any assigned constant energy surface of phase space is topologically accessible.

    • note
    • We assume that even for the small amplitude considered by FPU a finite threshold exists, so that we can extrapolate our results to the FPU case.
