摘要: 本文综合利用Lyusternik-Vishik[1]的渐近方法和不动点定理研究了具有非线性边界条件的非线性微分方程组的奇摄动,在适当的条件下证得解的存在性并给出N-阶渐近展开式和有关的余项估计.Abstract: In this paper, the singular perturbation of nonlinear differential equation system with nonlinear boundary conditions is discussed. Under suitable assumptions, with the asymptotic method of Lyusternik-Vishik[1] and fixed point theory, the existence of the solution of the perturbation problem is proved and its uniformly valid asymptotic expansion of higher order is derived.
