一类具有脉冲和多延迟的离散SI模型的持久性分析

摘要

研究一类具有脉冲和多延迟的离散SI模型,以原有的连续SI模型为基础,利用Euler法建立相应的离散模型,研究此离散模型的持久性,给出模型持久性的充分条件.%Consider a class of discrete SI model with impulse and multiple delays.On the basis of the original continuous SI model,the corresponding discrete model is established by the Euler method.The persistence of the discrete SI model is studied,and the sufficient conditions for the persistence are given.
