摘要
研究一类具有脉冲效应和Beddington-DeAnglis功能反应的时滞周期捕食系统,给出系统持续生存和周期解存在的条件.证明了在无时滞情况下,周期解是全局稳定的.
Periodic delayed predator-prey system with Beddington-DeAnglis functional response and impulsive effect is studied.The sufficient conditions for the permanence and existence for periodic solution of the above system are derived,and we prove that the periodic solution is globally stability without time delay.
