摘要
讨论了各向异性网格下线性三角形有限元对具有积分型边界条件的积分微分方程的逼近问题.通过引入新的技巧与方法,得到了相应的超逼近性质和超收敛性结果,从而进一步拓宽了有限元的应用范围.
Linear triangular element is considered to solve interracial and differential equation with interracial boundary condition on special restricted anisotropic meshes in 2D. The superclose property and superconvergence are obtained by a set of novel techniques. Thus the applicable scope of finite element method is extended.
