摘要
就一类二阶拟线性椭圆型方程,应用广义有限元方法,给出了有限元函数和导数的渐近展式和超收敛结果.数值例子验证了我们理论分析的正确性.
In this paper, we discuss a class of second order quasi - linear elliptic equation and obtain the asymptotic expansion and superconvergence of finite element function and derivative by using generalized finite element method. The numerical test convinces our analysis.
