摘要/Abstract

摘要：

该文考虑了移动环境下带有非局部扩散项和时滞的反应扩散方程的强迫行波解的存在性和唯一性. 首先利用上下解方法和单调迭代原理得到强迫行波解的存在性, 其中, 该强迫行波解以环境移动的速度来变化. 其次, 该文结合最大值原理, 利用挤压方法得到了该强迫行波解的唯一性. 最后, 作为该文得到的结论的应用, 该文给出了两个经典的模型, 一个是带非局部扩散项和时滞的Logistic模型, 另一个是带有非局部扩散项和时滞的quasi-Nicholson's Blowfiles人口模型.

关键词: 强迫行波解, 时滞反应扩散方程, 非局部扩散项, 移动环境.

Abstract:

This paper is devoted to establish the existence and uniqueness of the forced waves for a general reaction-diffusion equation with time delay and nonlocal diffusion term in a shifting environment. We first obtain the existence of the forced waves with the speed at which the habitat is shifting by using super- and sub-solutions method and monotone iteration method. Then we will give the uniqueness by applying the sliding method with the strong maximum principle. Finally, these analytical conclusions are applied to the nonlocal delayed Logistic model and the nonlocal delayed quasi-Nicholson's Blowfiles population model.

Key words: Forced waves, Delayed reaction-diffusion equation, Nonlocal diffusion, Shifting environment
