| Abstract: | The variational principle is used to find the dark soliton solution with fifth-order nonlinearity effect. It has derived the picture of the excursion of the center place of dark soliton with fifth-order nonlinearity effect using the method of numerical simulation. Then it analyses and discusses the influence of fifth-order nonlinearity effect on propagation properties of dark soliton. |
