摘要: 考虑一类具饱和发生率的随机SIR传染病模型, 用Markov半群理论证明了当Rs0>1时系统有唯一稳定的平稳分布.

关键词: 平稳分布, Markov半群, 饱和发生率, 渐近稳定性

Abstract: We considered a class of stochastic SIR epidemic models with saturated incidence. By using Markov semigroup theory, we proved that the system had a unique stable stationary distribution when Rs0>1.

Key words: asymptotic stability, Markov semigroup, saturated incidence, stationary distribution
