摘要
利用线性系统指数二分性理论和不动点定理,研究了一类具无限时滞的高维中立型脉冲积分微分方程概周期解的存在性问题,获得了保证中立型系统概周期解存在性和唯一性的充分条件,推广了相关文献的主要结果.
In the paper, the existence and uniqueness of almost periodic solution of the higher dimensional neutral integro-differential equation with impulsive and infinite delay are studied. By using the theory of exponential dichotomy of linear system and fixed point theorem, some sufficient conditions that guarantee the existence and uniqueness of almost periodic solution of the system are obtained. The conclusions made in the relevant documents is extended.
