摘要
提出了一种完全新型的有限元,称为(?)'型(或(?)'型)Lagrange有限元。用它可以减少工作量,且能保证高精度。同时,给出了这种有限元的一系列超收敛估计。
In this paper, we provide a completely new kind of finite element, which is called (?)'_k (or (?)'_k) Lagrange element. Not only does it reduce amount of work, but it pledges high order accuracy. Morever, we give a seral of superconvergence estimates of this finite element.
