Stationary patterns of a Leslie-Gower-type three-species model with cross-diffusions. (Chinese. English summary) Zbl 1289.92042

Summary: This paper is concerned with a Leslie-Gower-type three-species model subject to the homogeneous Neumann boundary condition. We show that under certain hypotheses, even though the unique positive equilibrium is asymptotically stable for the dynamics with diffusion, Turing instability can occur due to the presence of the cross-diffusion. In particular, we establish the existence of non-constant positive steady states of this system. The results indicate that cross-diffusion can create stationary patterns.
