报告摘要：
In this talk, we discuss the dynamics of traveling wave solutions connecting different equilibria for a spatial eco-epidemiological predator-prey system in advective environments. After applying the traveling wave coordinates, these solutions correspond to heteroclinic orbits in phase space. We investigate the existence of the traveling wave solution connecting from a boundary equilibrium to a co-existence equilibrium by using a shooting method and constructing Lyapunov-type function. Furthermore, the existence of traveling wave solutions between co-existence equilibria are also proved by utilizing the qualitative theory and the geometric singular perturbation theory.
