Abstract
We investigate with numerical methods the scaling of the relaxation time to equipartition in the celebrated Fermi-Pasta-Ulam model. Our numerical results strongly suggest that the time increases exponentially with an inverse power of the specific energy. Such a scaling appears to remain valid in the thermodynamic limit.
