摘要
利用线性系统的指数型二分性和Krasnoselskii不动点定理,研究一类中立型无穷时滞脉冲微分方程的周期解存在性问题,给出了保证系统存在周期解的一组充分条件,推广并改进了现有文献中的相关结论.
For a neutral of periodic impulsive differential system with infinite delays, the existence of periodic solutions was considered by using exponential dichotomy and fixed point theorem of Krasnoselskii. Sufficient conditions were given to guarantee the existence of periodic solutions of these equations under some assumptions. Some results in the literature had been generalized.
