Abstract
We establish the long-time stability of low-energy solitary waves in one-dimensional nonintegrable lattices with Hamiltonian
H = Sigma(jis an element ofZ)((1)/(2)p(j)(2) + V(q(j+1) - q(j)))
with a general nearest-neighbour potential V. As a corollary we obtain a recurrence theorem related to numerical observations by Fermi, Pasta and Ulam.
