摘要

了解可变系数和退化扩散对反应扩散方程解的长期行为的影响是很有意义的。最近，Yang 和 Yao（2024）研究了一个经典的猎物-捕食者模型，证明了满足适当条件的猎物扩散系数和可变系数的退化不会影响动力学性质。在本注释中，我们将简化 Yang 和 Yao (2024) 的证明，删除条件 (4)。

Note on the diffusive prey-predator model with variable coefficients and degenerate diffusion

It is of interest to understand effects of variable coefficients and degenerate diffusion on the longtime behaviors of solutions of reaction diffusion equations. Recently, Yang and Yao (2024) studied a classical prey-predator model and proved that the degradation of the diffusion coefficient of the prey and variable coefficients satisfying the appropriate conditions will not affect dynamical properties. In this note we shall simplify the proof of Yang and Yao (2024) and delete the condition (4).
