一类一阶中立型泛函微分方程周期解的存在与唯一性

Existence and Uniqueness of Periodic Solutions for a Class of First Order Neutral Functional Differential Equations

利用重合度理论研究并获得了如下一类一阶中立型泛函微分方程T-周期解的存在与唯一性(x(t)+Bx(t-δ))′：g1(t,x(t))+g2(t,x(t-τ(t)))+p(t)．

In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of T-periodic solutions for the first order neutral functional differential equation of the form （x（t）＋Bx（t-δ））＇=g1（t,x（t））＋g2（t,x（t-τ（t）））＋p（t）.
