摘要
讨论了一类奇摄动椭圆型方程的边值问题 ,在适当的条件下 ,构造了奇摄动问题的包括边界层在内的形式渐近解 。
In this paper,a class of singularly perturbed boundary value problems for elliptic equations are considered.Under appropriate conditions ,the formal solution of the singularly perturbed problem including boundary layers is constructed,and the uniformly validity of the formal solution is showed by using maximum principle.
