【 摘 要 】

This paper considers the existence of extreme solutions of the periodic boundary value problems for second order functional differential equations. A new concept of lower and upper solutions is introduced. And we present a new comparison principle. Meanwhile, we extend previous results. (C) 2004 Published by Elsevier Inc.
