摘要
利用重合度理论中的延拓定理,研究了一类具有Beddington-DeAngelis功能反应的空气污染周期动力学模型的正周期解的存在性,得到了该模型存在正周期解的充分条件。
In this paper,the existence of positive periodic solutions of a periodic air pollution dynamic model with Beddington-DeAngelis functional response is investigated by using the continuation theorem in coincidence degree theory,and a sufficient condition for the existence of positive periodic solutions of the model is obtained.
