主要研究一类具有双参数的拟线性微分方程的奇摄动Robin边值问题.利用微分不等式理论,对两参数分三种不同情形对解的构造进行分析.并得到相应问题在各情形下的渐近解和余项估计.
In this paper, a class of singularly perturbed Robin boundary value problems of quasi- linear differential equation with two parameters is studied. Using the method of differential in- equalities, the structure of solutions for the problems is discussed in three different cases about two small parameters. In addition, the asymptotic solutions have been found and the remainder term are given as well.
