摘要
利用具有各向异性特征的双线性元和双二次元对Sobolev方程进行Galerkin逼近,摆脱了对网格剖分满足正则性条件的要求,同时,利用积分恒等式技巧,得到了与传统方法相同的超逼近结果。
In this paper, Galerkin approximation of Sobolev equation is studied with anisotropic bilinear and biquaratic elements without the restriction of the regularity of triangulation. Meanwhile, the superclose result coincides with the conventional methods is obtained by means of integral identities techniques.
