摘要
本文用有限元方法研究椭圆型偏微分方程奇异摄动问题。我们构造了一种特殊的有限元子空间,当网格参数取特定值时得到一致收敛的有限元离散化。
By applying finite element method, this paper discussed a singular perturbation problem of elliptic partial differential equation, and constructed a special finite element subspace. Choosing the special values of net parameters, We obtained a uniformly convergent finite element discretization.
