利用微分不等式及Liapunov泛函,研究了一类具有时滞和Modified Leslie-Gower Holling Ⅱ功能性反应捕食-食饵系统,获得了系统一致持久及解全局吸引的充分条件,对于这类概周期系统,建立了存在全局吸引的唯一正概周期解的准则.
Existence and Global Attaractivity of Unique Positive Almost Periodic Solution for A Predator-Prey Model with Delay
In this paper,by using differential inequality and Liapunov function,we study the predator-prey model with delay and Modified Leslie-Gower Holling Ⅱ schemes.Sufficient conditions are obtained wich guarantee the uniform persistence and global attractivity of positive solution for the model.Then some criteria are established for the existence,uniqueness and global attaractivitv of positive almost periodic solution for almost periodic system.
