報(bào)告題目:Asymptotic profiles of basic production number for epidemic spreading in heterogeneous environment
報(bào)告摘要:In this talk, I will firstly consider the effect of diffusion rates on the basic reproduction number of a general compartmental reaction-diffusion epidemic model in a heterogeneous environment. It is shown that when the diffusion rates tend to zero, the limit of the basic reproduction number is the maximum value of the local reproduction number on the spatial domain. On the other hand, when the diffusion rates tend to infinity, the basic reproduction number tends to the spectral radius of the average next generation matrix. Then I will show some applications of Tree-Cycle identity on the SIS patch model and Lotka-Volterra competition patch model. This is a joint work with Professors Junping Shi, Zhisheng Shuai and Yixiang Wu.
時(shí) 間:10月31日下午17:00.
