摘要
研究捕食者具有非单调功能反应和周期脉冲扰动的捕食者 食饵系统,利用脉冲微分方程的Floquet理论和比较定理, 得到了系统灭绝和持续生存的充分条件. 最后, 通过数值模拟阐明系统在周期脉冲扰动下的复杂性.
We investigate the predator-prey system with non-monotonic functional response and periodic impulsive perturbations on the predator. By using the Floquet theory of impulsive equation and comparison theorem, sufficient conditions for the system to be extinct and permanence are given. Lastly, use the numerical simulation to illustrate the complexity of the system resulted from the periodic impulsive perturbation.
