| Abstract: | In this paper, the stabilities of boundary equilibrium and positive equilibrium of two_species Ayala competitive systems with two different diffusions are disscused, and dynamical behaviors of species is obtained. At the same time, the dynamical behaviors between systems with diffusion and those without diffusion are compared. This shows the influence of diffusions on the persistence of species. |
