Global attractivity in delay "food-limited" models with exponential impulses

In this paper, we are concerned with the global attractivity of the positive equilibrium of the following delay "food-limited" model with exponential impulses: {N'(t) = p(t) N(t) (1-N(t-tau))/(1+lambdaN(t-tau)), t greater than or equal to 0, t not equal t(k), {N(t(k)(+)) = N (t(k))(1+bk), k is an element of N, where p is an element of PC ([0, +infinity)) with p > 0, lambda is an element of (0, + infinity), tau > 0, b(k) > -1 for all k is an element of N. The initial condition is x(t) = phi (t), t is an element of [-tau, 0], where phi is an element of PC([-tau, 0]). The results obtained are new. (C) 2003 Elsevier Inc. All rights reserved.
