| Abstract: | Several fixed point theorems for contraction type mapping are obtained in this paper, which generalize and improve the corresponding results in 1-5]. As an application, some existence results of positive almost periodic solutions for delay integral equations are obtained, which generalize the existing results. |

| Keywords: | fixed point theorem almost periodic solution delay integral equation |
