关于一类Crouzeix-Raviart型非协调有限元误差分析的不等式

An Inequality in the error estimates of Crouzeix-Raviart noncomforming finite element method

关于一类Crouzeix-Raviart型非协调单元,本文给出了从边界积分到单元积分的一个不等式∫Kv2ds≤C(hk)∫Kv2dxdy中C(hk)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 explicity of C（hk） in the following inequality ∫δkv^2ds≤C（hk）∫kv^2dxdy is given for Crouzeix-Raviart noncomforming finite element, which is very important to its error estimate analysis.
