The variational iteration method for the soliton solution of nonlinear generalized Landau-Ginzburg-Higgs equation
非线性广义Landau-Ginzburg-Higgs方程孤子解的变分迭代解法

Using the perturbation method, a class of nonlinear generalized Landau-Ginzburg-Higgs equations are studied. Firstly, by introducing a varitational iteration, the Lagrange multiplicator is accounted for. Then the iteration of the solution for original equation is constructed and the approximate solution is obtained.
