摘要
研究了一类捕食者相互干扰和周期脉冲扰动的捕食-食饵系统,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.
A predator-prey system with mutual interference and periodic impulsive perturbations on the predator are considered, and the sufficient conditions for the system to be extinct and permanence are obtained by using the Floquet theory of impulsive equation and comparison theorem.
