摘要
结合应用指数型二分性原理和Schaefer定理,考虑了一类完全非线性泛函微分方程概周期解的存在性问题,改善和推广了已有的结果.并将获得的结果推广到周期系统,获得了一些新的结果.
By using of exponential principal and Schaefer theorem, the existence of almost periodic solutions for almost periodic systems with deviating argument was investigated. The obtained results are improved and generalized. Later, we extend our results to the periodic systems, and get some new results.
