摘要
For the equation, N (t) = r (t) N (t)/1 + [N (t)](gamma) - b(t) N (t) - a(t) N(g(t)), we obtain the following results: boundedness of all positive solutions, extinction, and persistence conditions. The proofs employ recent results in the theory of linear delay equations with positive and negative coefficients. (c) 2005 Elsevier Ltd. All rights reserved.
