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

Abstract

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
