| Abstract: | This paper is concerned with the periodic positive solutions of the first order functional differential equations with periodic delays. Some new existence results are obtained by using the Leggett-Williams fixed point theorem and Guo-Krasnosel＇skii fixed point theorem of cone expansioncompression. |
