Keywords:
Finite element, Superconvergence interpolant postprocessing.Abstract
The post-processing procedure is given by an interpolant postprocessing of the finite element solution by appropriately-defined finite dimensional subspaces. The corresponding superconvergence is established on general quasi-regular finite element partitions.
