报告题目：Traveling wave solutions of a class of multi-species non-cooperative  reaction-diffusion systems

报告摘要：In this talk, we establish a sharp existence result on weak traveling wave solutions for a general class of multi-species reaction-diffusion systems. Moreover, the minimal speed of the traveling waves is explicitly determined. Such a weak traveling wave solution connects the predator-free equilibrium point at -\infinity but needs not to connect the coexistence equilibrium at +\infinity. We apply this  result to three important non-cooperative systems: the classical diffusive SIS system with mass-action transmission  mechanism for the spread of infectious disease, a predator-prey system with age structure and a generalized Lotka-Volterra predator-prey system of one predator species  feeding on n prey species, and prove  that their weak traveling wave solutions are actually traveling wave solutions that connect  the coexistence equilibrium at +\infinity.This is a joint work with Shangbing Ai (University of Alabama, USA), Yihong Du (University of New England, Australia) and Yujuan Jiao (Northwest Minzu University, China).
