二阶奇摄动非线性微分差分方程组边值问题

Boundary Value Problems of second order singular perturbed nonlinear Differential Systems.

本文讨论一类二阶奇摄动非线性微分差分方程组的边值问题。证明了解的存在性，唯一性。给出了解的渐近展开式，并进行了余项估计。

In this paper,We discuss a class of boundary Value problems of second order singular perturbed nonlinear differential difference systems.We prone the existence and uniqueness of the solution of the problem.The asymptotic expansion of the solution is obtained and We prove that the expamsion is uniformly valid.
