THE INTERPOLATION POSTPROCESSING FOR THE FINITE ELEMENTRITZ-VOLTERRA PROJECTION
有限元Ritz-Volterra投影的插值后处理

Using the interpolation postprocessing technique, some asymptotically exact a posteriori error estimates and global superconvergence results are derived for the finite element Ritz-Volterra projection. These results are also given for the finite element approalmation to Sobolev equations.
