摘要
研究了一类具有小时滞的阶段结构SIS模型的渐近稳定性,我们得到了系统的平衡点的渐近稳定的充分条件,并用matlab软件进行了数值模拟,证实了所得结论的正确性,鉴于考虑的模型具有小时滞,所得结果是前人工作的继续和补充.
In this paper,the stability of a class of stage structure SIS model with small delay is studied. The sufficient conditions for asymptotical stability of the equilibrium are given. Some simulations are carried out by matlab software to support the correctness of our analysis results. Owing to the small delay , the results are the continuation and complement of the previous authors.
