摘要
研究一类基于比率依赖反应函数和改进的Leslie-Gower反应函数的捕食-食饵反应扩散模型。利用线性化方法、Lyapunov函数方法和比较原理,给出模型存在唯一正常数解、正常数解局部和全局稳定的充分性条件以及非常数正解的长时行为结果。
A predator-prey model with ratio-dependent and modified Leslie-Gower type functional responses is considered. Using the linearization method, the Lyapunov functional method and the comparison principle of parabolic equations, it is given that some sufficient conditions for the existence and uniqueness, the local and global stability of positive constant solution, and the largetime behavior results for nonconstant positive solutions.
