摘要: 用重合度理论研究二阶非线性泛函微分方程 x″(t)+f(x(t))x′(t)+g(x(t-τ(t)))=p(t)的周期解存在性, 得出了该方程存在T(T>0)周期解的两个充分性定理.

Abstract: In this paper, the theory of coincidence degree is used to study the existence of a periodic solution for the second order non-linear functional differential equation: x″(t)+f(x(t))x′(t)+g(x(t-τ(t)))=p(t), and two sufficient theorems are obtained for the existence of a periodic solution of T(T>0) of the equation.

Key words: second order, functional differential equation, periodic solution
