摘要
运用迭合度理论和分析的技巧,研究一类具分布时滞的中立型高阶泛函微分方程,并得到了其周期解存在的充分条件。
By using the theory of coincidence degree and some analytical skills, the periodic solution to a kind of lfigh - order neutral functional differential equation with distributed delay is studied. A sufficient condition on the existence of periodic solutions for this kind of neutral functional differential equation is obtained.
