摘要：

In this article, we investigate the existence of positive periodic solutions for a class of functional differential equations. By using fixed point index theory, we establish sufficient criteria that are easily verifiable and that generalize and improve related studies in the literature. Also, we give some examples in bio-mathematics to show that our main results are valid. (c) 2007 Published by Elsevier Inc.
