一类二阶微分方程奇摄动问题

The Singularly Perturbed Problem for Second Order Differential Equations

研究了一类二阶微分方程奇摄动Robin问题的角层解,在一定条件下利用微分不等式理论证明了角层解的存在性并讨论了近似解的渐近性态.

This paper studies corner layer solutions of Robin singularly perturbed problems of a class of second order differential equations, proves the existence of corner layer solutions and discusses asymptotic behavior of ap- proximate solution using the theory of differential inequality under certain conditions.
