应数学与统计学院邀请,加拿大纽芬兰纪念大学赵晓强教授为院师生作学术报告。

报告题目:Basic Reproduction Numbers for Reaction-Diffusion Population Models

报告摘要:The basic reproduction number (or ratio) R0 is an important concept in populationbiology. As a threshold quantity for population dynamics, it is unquestionably oneof the most valuable mathematical ideas brought to theoretical ecology and epidemiology. In this talk, I first review the definition, stability equivalence, numerical computation of R0 for reaction-diffusion systems with compartmental structure. Then I introduce a spatial model of Zika virus transmission with seasonality and establish a threshold type result on the global stability in termsof R0. Finally, I present numerical simulations for the Zika transmission in Rio de Janeiro Municipality, Brazil and briefly discuss the effects of some model parameters on R0.
