研究一类一般的二阶非线性方程的奇摄动Robin问题的边界层现象.在退化解是局部弱稳定的主要假设下,利用界定函数法和微分不等式理论证明了呈边界层性态的解的存在性,并给出解的渐近估计.
Boundary layer phenomena for some singularly perturbed Robin prob- lems of second-order nonlinear equations are considered. Under the principal assumption that a reduced solution is locally weak stable, the existence of solution which exhibits the boundary layer behavior is proved, and the asymptotic estimation of solution is given using the method of bounding functions and the theory of differential inequality.
