摘要
本文研究了一类具有转向点的二阶非线性方程奇摄动问题。利用微分不等式方法,证明了解的存在性,并得到了它的渐近估计式。
In this paper, a singularly perturbed problem with turning point for nonlinear equations of second order is considered. Using the method of differential inequalities, we proved that there exists a solution and obtained its asymptotic estimation.
