    Periodic Travelling Waves of Forced FPU Lattices

    No full text
    In this article, damped Fermi-Pasta-Ulam-type lattices driven by extended external forces are considered. The existence and uniqueness results of periodic travelling waves of the system are presented. The existence and the stability of periodic waves are also computed and discussed numerically. © 2013 Springer Science+Business Media New York
