通过构造一个特殊的闭凸集,利用著名的Mónch不动点定理,在Banach空间中获得了一类奇异脉冲微分-积分方程正解的存在性,所使用的方法本质上不同于已有文献.
By constructing a special closed convex set and using the Mónch fixed point theorem, we obtained the existence theorem of positive solution for first order singular impulsive integro-differential equation of mixed type in Banach space. The method used here is different in essence from that in the literature.
