摘要:

该文研究一类带有中立型脉冲时滞和Holling-IV型功能反应函数的捕食-食饵模型.通过运用Mawhin迭合度理论和分析技巧,得到了捕食-食饵模型正周期解存在性的充分条件.

关键词: 中立型捕食-食饵模型, 脉冲, 周期解, Holling-type IV型功能反应函数, 迭合度理论

Abstract:

This paper is concerned with a neutral impulsive predator-prey model with Holling-type IV functional response and delays. We obtain sufficient conditions on the existence of positive periodic solutions of this predator-prey model by using the Mawhin coincidence degree theory and analysis technique.

Key words: Neutral predator-prey model, Impulsive, Periodic solutions, Holling-type IV functional response, Coincidence degree theory
