本文讨论了一类具有奇性方程的奇摄动初值问题.在适当条件下,利用微分不等式理论,研究了初值问题解的存在性及其渐近性态,并且得到了具有初始层的一致有效解的渐近展开式.
A class of singularly perturbed initial value problem with singular equation is considered.Under suitable conditions,by using the theory of differential inequalities the existence and asymptotic behavior of solution for initial value problem are studied,and obtained uniformly valid asymptotic expansion of solution with an initial layer.
