摘要
在已有的理论基础上研究二阶非线性微分方程三点边值问题的微分不等式理论与解的存在性.然后利用所得的结果研究二阶拟线性微分方程三点边值问题的奇异摄动现象及解关于退化解的误差估计.
The theory of differential inequalities and the existence of solutions of a class of three-pointed boundary value problem for second order nonlinear differential equations are considered baseing on the existenced results. Then the results obtained is applied to research the singular perturbation differential equation of three-pointed boundary value problem for second order selinear differential equations. Furthermore, error estimate of the solution is gived.
