题目：Traveling wave solutions in a two-group SIR epidemic model with latent period
报告人: 王智诚教授 兰州大学
Abstract： We investigate full information on the existence and nonexistence of traveling waves of a two-group SIR epidemic model with latent period. We consider two cases: with or without vital dynamics. For both two cases, we show that when the basic reproduction ratio $R_{0}$ is larger than one, there exists the minimal wave speed $c^*>0$ such that for each $c>c^*$, the system admits a nontrivial traveling wave solution with wave speed $c$, and for $c 时间：2017年5月8日（周一） 15:30-16:30 地点：首都师范大学新教2楼 524 教室 欢迎教师和研究生积极参加！
