摘要

本文研究了一类带线段转向点的奇摄动椭圆型微分方程的边值问题。首先,利用多尺度方法我们构造除了带线段转向点的形式近似解;然后,借助比较定理,我们证明了解的近似展开式的一致有效性。

Abstract

In this paper,boundary value problem for a class of elliptic differential equations with a segment of turning points is considered.Firstly,using the method of multiple scales the formal asymptotic solution with turning points in constructed.And then,the uniform validity for the asymptotic expansion of the solution is proved by using the comparison theorem.
