Solutions, bifurcations and chaos of the nonlinear Schrodinger equation with weak damping

摘要

Using the wave packet theory, we obtain all the solutions of the weakly damped nonlinear Schrodinger equation.These solutions are the static solution, and solutions of planar wave, solitary wave, shock wave and elliptic functionwave and chaos. The bifurcation phenomenon exists in both steady and non-steady solutions. The chaotic and periodicmotions can coexist in a certain parametric space region.
