| Abstract: | Introducing symmetrical expansion and nonlinear transformation, the (G'/G)-expansion method is extended to investigate a nonlinear coupled Schrödinger system. Some exact solutions with variable separation are constructed for the system. The solutions involve two arbitrary functions of independent variables. By setting properly the arbitrary functions in the solutions, two types of folded solitons with periodic vibration are observed. |
