【Abstract】 We are concerned with the stationary problem of a Ivlev-type predator-prey model with crossdiffusion and a protection zone. The existence of coexistence states is discussed by using the eigenvalue theory and bifurcation theory. As a result, it is shown that the cross-diffusion is beneficial for species coexistence.更多还原
