摘要
研究了具有Beddington-Deangelis类功能反应的时滞食物链捕食者-食饵系统模型,得到了与时滞有关的系统永久持续生存的充分条件,同时通过构造Lyapunov函数得到了与时滞有关的系统全局渐近稳定的充分条件,是对文献[5]结果的进一步推广和改进。
A bait system model of delayed food chain systems with Beddington Deangelis type of functional response is studied. Sufficient conditions are obtained for the permanently sustained survival of the system related to time delays. Moreover, by using Lyapunov function, some conditions for globally asymptotic stability of the system are investigated. The results improved and generalized the main results in literature .
