二阶特征值问题的非协调元逼近

Nonconforming Elements Approximation for 2TH-order Eigenvalue Problem

利用紧算子谱逼近理论，给出了二阶特征值问题的非协调有限元逼近及相应的特征值误差估计，得到了利用协调元时相同的收敛效果．

In this paper.Nonconforming finite clements approximation for 2th-order cigenvalue Problem and the corresponding eigenvalue crror estimates are given by using compact spectral approximation thcory,Same convergence results with conforming finite clements are obtained.
