摘要
对一类具有饱和传染力的Schoner竞争系统进行了研究,得到了系统持久生存和任一正解全局渐近稳定的充分条件;同时当系统是概周期系统时,通过构造适当的Liapunov函数,建立了相应系统存在唯一、全局渐近稳定的概周期正解的充分判据.
A Schoner competitive system with saturated infectious force is studied in this paper. Some sufficient conditions for the persistence and the global asymptotic stability of any positive solution are obtained. What＇s more, when the system is almost periodic, it proved that there is a unique and global asymptotic almost periodic solution by constructing certain Liapunov function.
