摘要
本文建立了一类疾病在食饵当中传播的捕食—食饵模型,并利用泛函微分方程中的单调凸算子理论,获得了系统正周期解存在性和稳定性的充分条件.
In this paper, we consider a predator-prey model with a disease in the prey and by using the theory of monotone and concave operators of functional equations, the sufficient conditions of the existence and stability of a positive periodic solution for the system are established.
