报告题目：Concentration behaviorsof endemic equilibrium forsomereaction-diffusion-advection SIS epidemic models

报告摘要：We are concerned withseveralreaction-diffusion SIS epidemic models in advective heterogeneous environments, and investigate the combined effect of spatial heterogeneity and individual dispersal on dynamics of infected diseases.Threshold-type results on the global dynamics in terms of the basic reproduction number are established. We further investigate the effects of diffusion, advection and mechanism on asymptotic profiles of the endemic equilibrium. The individuals concentrate at the downstream end when the advection rate tends to infinity. The results may provide some implications on disease control and prediction.
