摘要:

 通过引进等价的范数,应用Banach不动点定理,在较宽松的条件下,获得了Banach空间中二阶非线性脉冲微分积分方程初值问题解的存在与唯一性及解的迭代逼近.对文[5](J.Math.Anal.Appl.200(1996),1-13)相应于d0=0的结果作了重要改进和推广. 该文条件易于判断,方法也本质地不同于文[5].

关键词: 非线性脉冲方程, 初值问题, Banach不动点定理

Abstract:

Through intrducing the equivalent norm, by applying Banach fixed theorem, under simpler conditions, the author has obtained existence and uniqueness and iterative approximation of solution for initial value problems of nonlinear second order impulsive integrodifferential equations in Banach space, and improved and generalized the corresponding results of paper [5] for d0=0 (J.Math.Anal.Appl. 200(1996),1-13).The assumed condition in present paper is easy to be judged and the method is different essentially from the one in paper [5].

Key words: Nonlinearimpulsiveequation, Initialvalueproblem, Banachfixedpointtheorem
