報告題目：Global stability of a fractional order SIS epidemic Model

報告摘要：In this talk, I will introduce our new results about global stability of a fractional order SIS epidemic Model. By way of continuous time random walk, we establish a new fractional order SIS (frSIS) model and provide a framework for the global stability of the frSIS model, and prove that the basic reproduction number R0 can be used to govern the dynamics of the frSIS model: if R0<1, the disease-free equilibrium of the model is globally asymptotically stable; while if R0>1, the endemic equilibrium of the model is globally asymptotically stable. And epidemiologically, we find that, in order to control the spread of the disease, we must decrease the death rate and the average infectious period to make the disease go to extinction, which can provide us with some useful control strategies to regulate disease dynamics. This is a joint work with Zhaohua Wu, Yongli Cai and Zhiming Wang.
