Global stability of discrete population models with time delays and fluctuating environment

[摘要] The global stability of a discrete population model of Volterra type is studied. The model incorporates time delays and allows for a fluctuating environment. By linearization of the model at positive solutions and construction of Liapunov functionals, sufficient conditions arc obtained to ensure a positive solution of the model is stable and attracts all positive solutions.
