本文讨论了带有积分边界条件的二阶半线性奇摄动方程的脉冲状对照结构.借助于边界函数法,在一定条件下,构造了该问题的形式渐近解.利用缝接法证明了该问题解的存在性和形式渐近解的一致有效性.
In this paper,we investigate the spike-type contrast structure for a second order semi-lin- ear singularly perturbed differential equation with integral boundary condition. Under suitable condi- tions, using the boundary function method, we construct the asymptotic solution for this problem. At the same time, the existence of the solution and the uniform validity of the formal approximation are proved bv the rn~h~r! ~.~ ;
