摘要
利用重合度理论研究了一类具复杂偏差变元高阶泛函微分方程的周期解的存在性,在更广泛的条件下,得到了存在周期解的新结果.
Using the theory of coincidence degree,the existence of periodic solutions of a type of high order functional differential equation with complex deviating argument under the more universal conditions is studied,and some new results for the existence of periodic solutions are obtained.
