摘要 研究一类具有接种和迁移的多斑块SIV传染病模型的动力学行为.在适当的条件下,证明该模型存在平稳的马尔可夫过程,也得到感染者数量趋于灭绝的结果.最后,数值模拟验证了主要结果. We study the dynamical behaviors of a multi-group epidemic model with vaccination and migration.Under some appropriate conditions,we prove that SIV model admits a stationary Markov process,and also reveal that the numbers of the infected tend to the extinction.Numerical simulations finally verify our main results.
