| Abstract: | Professor Lin Qun has put forward an interpolated finite element method. This method is very powerful to improve the global convergence in second order elliptic boundary value problems. This paper uses the method to the Galerkin methods for numerical approximation of the coupled quasilinear system and obtains globally a one order higher convergence. |
