摘要 利用重合度理论研究了一类具有偏差变元的泛函微分方程周期解的存在性问题,得到了该方程具有周期解的一些充分条件.结论丰富了现有文献的结果. By using the coincidence degree theory, we study a kind of functional differential equations with deviating argumen. Some sufficient conditions for the existence of periodic solutions are presented and complement previously known results.
