摘要: 通过逐段应用推广的Darbo不动点定理,在较弱的条件下,给出了实Banach空间中一阶脉冲积分-微分方程初值问题整体解的存在性,改进了一些已有的结果.

Abstract: By using generalized Darbo's fixed point theorem step by step, under
weaker conditions, the authors present the existence of global solutions for initial value problems of first order impulsive integro-differential equations in Banach space. The results obtained improve and extend many known results.

Key words: First order nonlinear impulsive equation, Measure of noncompactness, Initial value problem, Global solution, Darbo''s fixed point theorem
