摘要
研究一类离散的两企业竞争模型的全局吸引性.运用差分方程的有关理论,得到保证该系统持久的充分性条件;其次,通过引入一个变换,得到在一定条件下,该系统是全局吸引的.
A discrete competition model of two enterprises is studied.By applying the theory of difference equation,sufficient conditions which guarantee the permanence of the system are obtained.Then by introducing a transformation,it shows the system is global attractivity under some conditions.
