报告摘要: In this talk, we present some recent results on propagation phenomenon for diffusive epidemic models with seasonal effect. The full information about the existence and non-existence of periodic traveling waves for diffusive and time periodic Kermack-McKendrick SIR epidemic model and nonlocal delayed reaction-diffusion SIR epidemic model. The time periodic traveling waves with critical speeds are also studied for Kermack-McKendrick SIR epidemic. We further introduce some results on asymptotic speeds of spread for diffusive epidemic model with demographic structures.
