THE POSTPROCESSING FOR GALERKIN METHODS FOR NONLINEAR SOBOLEV EQUATIONS
非线性Sobolev方程Galerkin解法的后处理与超收敛

The postprocessing for Galerkin methods for nonlinear Sobolev equations is studied in this paper.lt is proved that the estimates error in H1-and L2- norms after postprocessing can be improved by one order for both discrete and semi-discrete schemes as well as continuous time scheme has been proved when the degree of the standard finite element space is no less than two.
