Abstract:
In this talk I will report some recent results on the invading profiles of a two species competition model with free boundaries. We are interested in a complete classification of the invading profiles of the system in the weak-strong competition case, where a strong competitor and a weak competitor invade the spatial environment simultaneously. We show that there are exactly five different types of long-time invading profiles for this system. This talk is based on theoretical work with Chang-Hong Wu, and numerical work with K. Khan, Shuang Liu and T. Schaerf.
