Abstract
In this paper, we investigate the dynamics of a diffusive Leslie–Gower model incorporating a weak Allee effect on prey and a fear effect on predators. First, we derive the relevant characteristic equations. Subsequently, we analyze the existence of Turing Hopf bifurcation–phenomena that characterize the emergence of spatial patterns and temporal oscillations driven by diffusion and population dynamics, respectively. Finally, we perform numerical simulations to validate our theoretical results and further illustrate the model dynamics with both weak Allee and predator fear effects.
期刊介绍:
The purpose of Applied Mathematics Letters is to provide a means of rapid publication for important but brief applied mathematical papers. The brief descriptions of any work involving a novel application or utilization of mathematics, or a development in the methodology of applied mathematics is a potential contribution for this journal. This journal''s focus is on applied mathematics topics based on differential equations and linear algebra. Priority will be given to submissions that are likely to appeal to a wide audience.
