摘要
本文利用迭合度理论讨论一类有偏差变元的泛函微分方程的2π周期解的存在性,得到一个充分判据,推广了文献[1]、[2]的有关结果。
In this paper,the theory of coincidence degree is used to study the existence of the periodic solutions for a class of functional differential equations with partial difference variables and a new result is obtained,which is the improvement of the theorem in the previons papers.
