主要考虑了一个带有自扩散和交差扩散的空间分布非均匀的年龄结构模型,基于相应的常微分模型利用Liapunov方法得到了一致稳态的全局稳定性,进而也讨论了扩散效应对于稳定态的作用。
In this paper we propose a spatial nonhomogeneous stage-structured predator-prey model with self and cross-diffusion. The global stability of the uniform steady state can be derived basing on the stability of the corresponding ordinary differ-ential system using Liapunov function method. The effect of diffusion on the stability of the system is also investigated.
