摘要
通过构造适当的Lyapunov绝灭函数,研究了一类离散非自治竞争系统,得到了保证系统中某个种群绝灭和另外一个种群全局吸引的充分性条件,所得的结果补充了前人的工作.
A class of discrete non-autonomous competitive system of two species is considered.By constructing some suitable Lyapunov type extinction functions,sufficient conditions which guarantee the extinction of species and the stability property of another species are obtain.The results supplement some known results.
