本文研究了Banach空间中两类具有一端点值固定边界条件的二阶脉冲积- 微分方程三点边值问题解的存在性,并且获得了完全不同的先验估计.

The present paper investigates the existence of solutions, with their values fixed at one end point, of two classes of three-point boundary value problems for the second order impulsive integro-differential equations in Banach spaces, and the a priori estimates obtained in both of the two cases are completely different.
