摘要
主要讨论了具有无穷时滞中立型Ｖｏｌｔｅｒｒａ积分微分方程的周期解的存在性。方法是构造适当的Ｌｉａｐｕｎｏｖ泛函，推出该方程至少有一个ω周期解存在。中立型积分微分方程；Ｂ空间；一致稳定；弱衰减记忆；一致有界；
he existence of periodic solutions of neutral Volterra integral differential equations with finite delay is discussed, with the method of structuring a suitable Liapunov function. It is proved that there exists at least one ω-periodic solution to the equation.
