| Abstract: |
| By using a continuation theorem based on coincidence degree theory, sufficient conditions are obtained for the existence of positive periodic solution for a class of a delay predator-prey system with monotonic functional response and impulsive effect.The results have improved and extend the related reports in the literatures. |
| Key words: differential equation predator-prey system impulsive effect monotonic functional response periodic solutions coincidence degree |
