摘要
先运用Lery-Schauder度的同伦不变性得到正则问题解的存在性原则,再运用该存在性原则和逼近的思想,研究带有积分边界条件的脉冲微分方程奇异边值问题,得到了该类问题正解的存在性.
The authors studied the impulsive differential equation singular boundary value problem with integral boundary condition.First,the Lery-Schauder degree homotopy invariance was used to prove the existence of solutions principle for regular problems,then the existence of positive solutions was proved by means of this existence of solutions principle and the idea of approximation.
