中文摘要

本篇論文主要探討具時滯參數之競爭系統的動態行為。首先,我們利用三種不同方法分析不具
時滯參數之競爭系統的整體穩定性。而後討論具時滯參數之競爭系統,在適當條件下系統之解是均勻持久的,進而得到此系統之唯一正均衡點的整體穩定性的充分條件。最後,我們舉例說明上述結果。

英文摘要

In this paper, we study the dynamical behavior of a competition system with time delay. We first use three different methods to analyze the global stability of the unique positive equilibrium point of the system
without time delay. Secondly, it is shown that the system with time delay is uniform persistent under some appropriate conditions, and sufficient conditions are obtained for the global stability of the unique positive
equilibrium point of the system with time delay. Finally, we illustrative our results by some examples.
