高阶有限元的超逼近

Superconvergence in high-order galerkin finite element methods

利用积分恒等式方法和局部对称化技巧讨论了泊松方程有限元超收敛性 .

This paper uses an integral ineguality method and symmetric point technique to deal with poission equation FEM solution and has achieved a better superconvergence result on rectangular meshes then before.
