摘要
本文是讨论一类在局部区域上的奇摄动非线性 Robin边值问题 .利用算子理论和不动点原理 ,得到了相应问题解的存在性和唯一性 .
A class of singularly perturbed Robin boundary value problems for nonlinear equations in a part of domain are considered.using the theorem of operator and fixed point theorem the existence and uniquence of solution for the problems are studied.
