摘要
考虑一类高阶微分方程ax(2n)(t)+cx(′t)+h(x(′t))x(t)+g[x(t-τ)]=p(t)利用重合度理论,获得了此类方程至少存在一个T-周期解的充分条件.
A class of high order differential equation is considered as follows ax^（2n）（t）＋cx′（t）＋h（x′（t））x（t）＋g[x（t-τ]=p（t） By using the theory of coincidence degree, a sufficient condition of existence at least one T - periodic solution is obtained.
