混合型线性微分差分方程边值问题

The Boundary Value Problem for Differential-Difference Equations with Mixed Type

本文讨论混合型奇摄动线性微分差分方程边值问题，在适当的条件下，证明了解的存在性、唯一性，给出了渐近解，证明了其一致有效性。

In this paper, we discuss a class of the boundary value Problem for differential -difference equation with mixed type, under certain Conditions, the existence and uniqueness of the solution of the BVP is Proved. The asymptotic expansion of the solution is obtained, and the expansion is uniformly valid.
