Abstract:
本文考虑具无限时滞非线性积分微分方程x’(t) = A(t, x(t))x(t) + C(t, s)x(s) ds + g(t, x(t - τ)) + b(t), (1)和x ’(t) = f(t, x(t)) + ∫t -∞ C(t, s)x(s) ds + g(t, x(t - τ)) + b(t), (2)其中t∈R,τ≥0是常数,x∈Rn;A(t,x),C(t,s)为n×n连续的函数矩阵;f(t,x),9(t,x),b(t)是n维连续向量.本文利用线性系统的指数型二分性理论和不动点定理研究此系统,建立了保证其周期解存在性.唯一性的充分条件.得到了一些新的结果,推广了相关文献的主要结果.
