摘要
考虑两类概周期系统,利用压缩映像原理和指数型二分性粗糙度理论,得到保证上述系统存在唯一概周期解及有界解的充分条件.所得结果推广或改进了一些已有的结果.
We consider the almost periodic perturbation systems. By using the contraction principle and the roughness theory of exponential dichotomies, some sufficient conditions are for the existence and uniqueness of almost periodic solution and bounded solution. Our results mapping obtained generalize those ones.
