内容介绍:In this talk we will mainly discuss the dynamics of two competing species in three-patch models and investigate how network topology may affect the evolution of dispersal in advective environment. Each model assumes that patch 1 is at the upstream end, patch 3 is at the downstream end, but patch 2 could be upstream, or middle stream, or downstream, depending on the specific topology of the modules. These models are described by systems of 6 ODE equations. Some predictions on the dynamics of n-patch models will be given. This talk is based on joint works with Hongyan Jiang and King-Yeung Lam.
