Scaling of the recurrence time in the cubic Fermi-Pasta-Ulam lattice. (English) Zbl 1063.82539
Summary: We re-examine the first recurrence time of the cubic FPU lattice as a function of the amplitude of the initial condition and the number of masses in the lattice. The parameter dependence of the recurrence time shows some novel features that are not explained by previous theoretical work.
