捕食-食饵系统在气候变化下强迫波的存在性

Existence of Forced Waves in a Predator-prey System under Climate Change

捕食-食饵系统是一种描述种群之间相互作用的数学模型,在维护生态平衡方面发挥着重要作用。研究了在气候变化环境下的一类三物种捕食-食饵系统,通过构造合适的上下解并结合Schauder不动点定理,得到了强迫波的存在性。

This paper is concerned about a three-species predator-prey system under a discrete shifting environment,and the existence of forced waves is obtained by using constructing appropriate upper-lower solutions and Schauder's fixed point theorem.
