摘要 讨论了带有Neumann边界条件的一类Leslie-Gower型三种群系统,在一定的条件之下,虽然系统对应的扩散(没有交错扩散)系统的唯一正平衡解是稳定的,系统中的交错扩散可导致Turing不稳定性的产生.特别地,建立了该系统非常数共存解的存在性.结果表明,交错扩散可引起系统中出现非常数正稳态解(稳态模式). This paper is concerned with a Leslie-Gower type three species model subject to the homogeneous Neumann boundary condition. We will show that under certain hypotheses, even though the unique positive equilibrium is asymptotically stable for the dynamics with diffusion, Turing instability can produce 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.
