| Abstract: | A nonlinear Galerkin method using spectral expansions is presented for thesteady nonlinear partial differential equations. We prove the existence, uniqueness andconvergence of the numerical solution corresponding to this method. Compared with the usualGalerkin method, the nonlinear Galerkin method is simpler under the same convergenceaccuracy. |
