摘要
本文考虑一类半线性椭圆型方程的边界层-角层现象,在适当的条件下,我们得到了摄动问题解的存在性及其一致有效渐近展开式.
In this paper,we consider the phenomenon of boundary-interior layer interaction for a class of semilinear elliptic equation. Under some appropriate conditions,we get the existence of the exact solution for the problem and its uniformly valid expansions.
