| In this paper,we mainly study a Darboux transformation of the four-component nonlinear Schrdinger-type equation,which is associated with a 3×3 matrix spectral problem.and construct exact solution.Firstly,based on the presentation of the Lax pairs,the fourcomponent nonlinear Schrdinger-type equation is introduced.Then the corresponding gauge transformation and Darboux transformation of the soliton equation are deduced.Finally,depending on the derived Darboux transformation,explicit solutions for the fourcomponent nonlinear Schrdinger-type equation are given and some figures are plotted by the proper choice of parameters. |
