摘要
We state sufficient conditions for the existence of positive pseudo almost periodic and asymptotically almost periodic solutions of the following nonlinear infinite delay integral equation: x(t) = integral(t)(-infinity) a(t,t - s)f(s, x(s))ds. Then we apply these results to a finite delay integral equation when the delay is time-dependent and to a delay differential equation. (c) 2008 Elsevier Ltd. All rights reserved.
