摘要
基于微分不等式方法,结合边界层校正的思想,研究了一类具有无穷大边界值的半线性奇摄动Neumann边值问题解的存在性、解的渐近近似以及渐近解的误差估计等.两个典型的算例表明:基于边界层校正思想所构造的渐近解是正确且一致有效的.
By combining the method of differential inequality with the idea of boundary layer correction,the existence and asymptotic approximation of solution of Neumann problems with infinite boundary values for semi-linear singularly perturbed differential equations is obtained.The error estimate between the asymptotic and the exact solutions are also obtained.Two typical examples are performed to verify the correctness and uniform validity of the asymptotic solution obtained by boundary correction.
