摘要
研究了一类具有Beddington-DeAndelis功能性反应和捕食者互相残杀项的非自治离散捕食系统,利用Mawhin重合度理论获得了这类系统正周期解存在的充分性判据.
It was studied that for the non-autonomous discrete predator-prey system with the Beddington-DeAndelis functional response and predator cannibalism. By using continuation theorem which was proposed by Gaines and Mawhin, the existence sufficient conditions of at least one positive periodic solution of the system are obtained.
