摘要
建立了具有Holling I功能反应的离散时滞捕食与被捕食模型,引用已有的结论证明了系统的永久持续性,并且构造Lyapunov函数证明了系统正解的全局吸引性.
In this paper,a discrete predator-prey model with time delay incorporating Holling I functional response is investigated,and permanence of the system is argued via citing previous results,and that the global attractivity of positive solutions of the system are testified by constructing a Lyapunov function.
