| Abstract: |
| In this talk I will report some recent progress on a free boundary model, where the free boundary conditions are deduced from the biological assumption that the species expands or shrinks its population range through its members at the range boundary keeping the population density there at a preferred level. It turns out that this strategy would make the species a super invader: No matter whether the growth function f(u) is monostable, bistable (strong Allee) or of combustion type (weak Allee), the species always spreads successfully. |
