Periodic Solutions with Invariant Amplitude for the Derivative Nonlinear Schrödinger Equation

Jinmei Liu, Changfu Liu, Ping Zhou


In this paper, a series of periodic solutions with invariant amplitude for the derivative nonlinear schrödinger equation are obtained by using trial function method. Two solutions’ images are displayed, which can help one understand their dynamical behavior better. These results enrich the solutions’ structural diversity for the derivative nonlinear schrödinger equation.
