摘要
考虑无穷时滞中立型泛函微分方程，其中，－∞＜θ≤０，关于ｔ是Ｔ周期的．我们先建立了一个映（－∞，０］到Ｒｎ的函数空间作为相空间．利用这个相空间得到：系统有界全局吸引子的存在性导出周期解的存在性．
The author considers a system of neutral functional differential equations with infinite delay , where , -∞ < θ ≤ 0. D,are T periodic in t,is a new phase space of functions that mapping (-∞, o] into Rn. By using the phase space ,the conclusion are given for the system that the existence of a bounded global attractor implies the ekistence of a T periodic solution.
