关于一个有限元误差分析的不等式

An Inequality in the Error Estimates of Finite Element Method

关于P1-非协调单元本文给出了从边界积分到单元积分的一个不等式∫K2υds C(hK)∫Kυ2dxdy中C(hK)中的具体值。它在相应的有限元误差分析中将起到关键的作用。

In this paper.the exphcity of C（hK） in the following inequality ∫K2υds ≤C（hK）∫Kυ2dxdy dxdy is given for P1 - noncomforming finite element, which is very important to its error estimate analysis.
