The dynamical behavior of a predator-prey system with Gompertz growth function and impulsive dispersal of prey between two patches

摘要

In this paper, we investigate a predator-prey model with Gompertz growth function and impulsive dispersal of prey between two patches. Using the dynamical properties of single-species model with impulsive dispersal in two patches and comparison principle of impulsive differential equations, necessary and sufficient criteria on global attractivity of predator-extinction periodic solution and permanence are established. Finally, a numerical example is given to illustrate the theoretical results. Copyright (C) 2015 John Wiley & Sons, Ltd.
