有限元校正方法的一个注记

A NOTE ABOUT THE CORRECTION METHOD OF FINITE ELEMENT

对凸多边形上的椭圆边值问题,Rannacher,R.建立了一个有限元校正格式。本文在自然假设下对Rannacher格式建立了误差估计式。

For elliptic boundary value problem on a convex polygonal domain, the correction method of finite element are posed in [1]. In this note, We deduce its error estimate under natural assumptions.
