Title: Invasion fronts in spatially extended systems
Invasion fronts refer to fronts propagating into unstable states. An important characteristic of such fronts is the speed at which they propagate. In this talk, I will review wavespeed selection principles and discuss two recent research projects related to wavespeed selection. In the first, we study the emergence of locked fronts in a class of two component reaction diffusion equations. In the second, a model of global epidemics is considered and predictions for arrival times are obtained based upon the linearization about the unstable steady state.
