The Discrete Nonlinear Schr6dinger equation, unlike its continuum counterpart, is nonintegrable in general. Here, we use Poincar6 spheres and spectral techniques to show some manifestations of chaos in this system. (.~ Crown copyright (1994).
We consider localized modes (discrete breathers) of the discrete nonlinear Schrödinger equation i( We study the diversity of the steady-state solutions of the form ψ n (t) = e iωt v n and the intervals of the frequency, ω, of their existence. The base for the analysis is provided by the anticontinu
