摘要
作者研究了具有非线性椭圆型方程奇摄动问题。在适当的条件下,利用微分不等式理论,讨论了当退化问题具有两个相交解时,原边值问题解的渐近性态。
The nonlinear singularly perturbed problems for the elliptic equations are considered. Under suitable conditions, using the theory of differential inequalities the asymptotic behavior of solution for the boundary value problems are studied, which reduced equations possess two intersecting solutions.
