摘要
利用Mawhin重合度拓展定理,研究了一类时滞Duffing型方程x″(t)+bxn+g(x(t-)τ)=p(t)(n>1),得到周期解存在的新结果,改进和推广了已有文献的结果.
By employing the continuation theorem of coincidence degree theory developed by Mawhin, we study a kind of Duffing equation with a delay as follows x″（t）＋bxn＋g（x（t-）τ）=p（t）（n〉1）A new result on the existence of periodic solutions is obtained. Our work improves and extends the results of literatures.
