摘要
考虑一类具有双参数的二阶拟线性微分方程奇摄动内层问题,在适当的条件下,利用微分不等式及内部层校正理论构造了该问题的上、下解,证明了解的存在性,并给出了解的渐近估计.
Singularly perturbation inner layer problems for a class of quasilinear second order differential equation with two parameters were discussed.Under appropriate conditions,specific upper and lower solutions were constructed,then prove the existence of the solutions;and the asymptotic estimate of solutions was given according to the theory of differential inequality and the correction of interior layer.
