摘要
利用重合度理论及Mawhin连续性定理,研究了一类具有脉冲时滞和Holling Ⅲ类功能反应的捕食者-食饵系统正周期解的存在性问题,得到系统存在正周期解的充分条件,并推广和改进部分已有结果。
By utilizing Mawhin＇s coindidence degree theory and Mawhin＇s Continuity theorem,a criterion for the periodic solution of the Holling Ⅲ predator-prey systems with time-varying delay is further investigated. The criterion improves several recent works. The sufficient conditions for the existence of positive periodic solution of the system is presented.
