摘要
考虑一类稀疏效应非自治 Volterra捕食—被捕食系统 .证明了该系统在某些条件下是持久的 ,而且 ,若该系统是周期系统 ,在某些条件下 ,它们存在唯一的严格正周期轨道 ,且是全局渐近稳定的 .
A nonautonomous Volterra predator prey system with undercrowding effect is considered.It is proved that the system can be made persistent under some approrpriate conditions.Further,if the system is a periodic system,it can have a strictly positive periodic orbit which is globally asymptotically stable under the approrpriate conditions.
