我們分析具時滯參數之Leslie-Gower Holling-Type II型捕食系統的局部及整體穩定性。首先我們分別探討不具時滯參數或具時滯參數之Leslie-Gower Holling-Type II型捕食系統的局部及整體穩定性。最後,用實例及電腦軌跡圖說明之。
In this paper, we analyze the dynamic behavior of a predator-prey model of modified Leslie-Gower and Holling-Type II with time delay. Firstly, we discuss the local and global stability for this system without time delay. Secondly, we find out some sufficient conditions for local and global stability of the unique positive equilibrium point of this system with time delay by constructing different Lyapunov function, respectively. Finally, we illustrate our results by some examples.
