| Abstract: |
| In this talk, we will introduce the sign of bistable wave speed and spreading properties of solutions for a class of three species competitive-cooperative reaction-diffusion systems. We first establish sufficient conditions for a species to be the winner, and then show that the species with large invasion speed can always establish a wave moving into open space with its own speed, while the others will be driven out or invade successfully, depending on the parameters, at a lower speed.
This is the co-work with professor Xiaoqiang Zhao in Memorial University of Newfoundland. |
