为非线性的椭圆形的方程的边界价值问题被考虑。原来的问题的外部解决方案被获得。边界和内部层修正条款被在边界和外部答案的内部不连续的点附近介绍拉长的变量和设置本地人坐标系统构造。在合适的条件下面,用微分不平等和吝啬的价值定理,边界价值问题的吃惊解决方案的存在被证明,答案的 asymptotic 行为被学习。
The boundary value problem for the nonlinear elliptic equation is considered. The outer solution for the original problem is obtained. The boundary and interior layer correction terms are constructed by introducing stretched variables and setting local coordinate systems near the boundary and interior discontinuous point of outer solution. Under suitable conditions, using the differential inequalities and the mean value theorem, the existence of the shock solution for boundary value problem is proved and the asymptotic behavior of the solution is studied.
