摘要
In this paper, we consider the impulsive differential equation {x'(t) = -a(t)x(t) + p(t) f(t, x(t - tau(0)(t)), x(t - tau(1)(t)) ...., x(t - tau(n)(t))) a.e, t > 0, t not equal t(k); x(t(k)(+)) - x(t(k)) = b(k)x(t(k)) By using a fixed point theorem, some criteria are established for the existence of a positive of omega-periodic solution of the above equation. Our work extends and improves some known results. (C) 2007 Elsevier Ltd. All rights reserved.
