摘要
本文研究两参数常微分方程初值问題的第二边界层现象,在适当的假定下,证明了解的存在唯一性,并作出了解的高阶一致有效渐近展开式。
In this paper we study the second boundary layer phenomena for initial value problems Of ordinary differential equations with two small parameters. Under adequate assumptions, we have proved the existenceand uniqueness of solution for initial value problem. Besides, the higher order asymptotic expansion of solution is constructed, which is valid uniformly in the domain.
