摘要
利用Mahwin重合度理论研究了一类具多偏差变元的高阶微分方程的周期解问题,得到了周期解存在性的充分性结果,推广和改进已有的结果.
By employing the continuation theorem of coincidence degree theory developed by Mawhin, a kind of higher order functional differential equation with multiple deviating arguments is studied. Sufficient conditions are given for the existence of periodic solutions, which generalizes and improves the known result.
