摘要
本文对一类带有转向点的非线性常微分方程奇摄动Robjn边值问题证明了解的存在性并给出了解的近似估计,特别地,在拟线性情形给出了解及其导数的一致有效渐近展开。
The present paper deaks with singularly perturbed Robin boundary value problems for second order nonlinear differential equations with turning point, proves existence of solution and asympotic estimation of it; especially for the quasilinear equations, the uniformly valid asymptotic expansions of solution and its derivative are given.
