摘 要:
本文讨论具有无穷时滞中立型泛函积分微分方程d/dt(x(t)-∫-∞^tB(t,s)x(s)ds=A(t,x(t))x(t)+∫-∞^tC(t,s)x(s)ds+^l∑i=1gi(t,x(t-τi(t)))的周期解问题。通过巧妙的构造算子,利用线性系统的指数二分性和Krasnoselskii不动点定理得到了周期解的存在性。我们的结果推广了相关文献的主要结果。[著者文摘]

Abstract:
In this paper,the periodic solution of a neutral integro-differential equation infinite delay of the following d/dt(x(t)-∫-∞^tB(t,s)x(s)ds=A(t,x(t))x(t)+∫-∞^tC(t,s)x(s)ds+^l∑i=1gi(t,x(t-τi(t)))are discussed. Some new results on existence of periodic solutions are obtained by using exponential dichotomies of linear system and Krasnoselskii's fixed theorem.[著者文摘]
