  title={Se p 19 96 The Fermi-Pasta-Ulam problem revisited},
  author={Lapo Casetti},
The Fermi-Pasta-Ulam α-model of harmonic oscillators with cubic anharmonic interactions is studied from a statistical mechanical point of view. Systems of N = 32 to 128 oscillators appear to be large enough to suggest statistical mechanical behavior. A key element has been a comparison of the maximum Lyapounov coefficient λmax of the FPU α-model and that of… CONTINUE READING
