    Connectance and equipartition thresholds in hamiltonian systems

    No full text
    The effect of increasing connectance (i.e. number of interacting neighbouring masses) on the equipartition threshold of a Fermi-Pasta-Ulam (FPU) model with 32 mass points is considered. Increasing the number of interacting neighbour mass points from 2 to 3, 4 and 5 and keeping constant the effective strength of the nonlinear terms no sensible effect on the critical energy for equipartition is observed
