Darboux Transformation Of A Generalized Four-component Derivative Nonlinear Schr(?)dinger Equation And Its Exact Solutions

In this thesis,we focus on analyzing a generalized four-component derivative non?linear Schr(?)dinger equation by using the Darboux transformation method.Depending on the spectral problems,we construct the associated Darboux transformation.Moreover,an explicit solution is obtained by using the Darboux transformation with taking the trivial solution,u=v=q=r=0 as seed solution.Finally,figures of solutions are given by using the Mathematica by choosing suitable parameters.
