摘要
In our paper, by employing Krasnoselskii fixed point theorem, we investigate the existence of multiple positive periodic solutions for functional differential equations x (t) = A (t, x (t)) x (t) + lambda f (t, x(t)), where lambda > 0 is a parameter. Some easily verifiable sufficient criteria are established. (c) 2006 Elsevier Inc. All rights reserved.
