二阶障碍问题的一个非协调矩形元逼近

A NONCONFORMING RECTANGLE ELEMENT APPROXIMA TION FOR SECOND ORDER OBSTACLE PROBLEM

本文讨论了二阶障碍问题的一个五自由度非协调矩形元逼近。证明了逼近解的收敛性,并在解u∈W^(2,p)(Ω)(p>2)的条件下,得到了一个误差估计。

In this paper, a five-degree nonconforming rectangle element approximation for second order obstacle problem is considered. The covergenee result is obtained, and the error estimate is shown if the solution u∈W^(2,p)(Ω) with p>2.
