三个年龄结构的单种群动力系统持续性与周期解的稳定性(英文)

Persistence and global stability of periodic solution for three stage structure single species dynamics system

建立了三个年龄结构的单种群动力系统,在这个系统中,种群可以分成三个阶段即幼年、成年和老年,证明了这个系统是持续生存的,在适当条件下,获得了这个系统周期解的全局渐近稳定性的充分条件.

The nonautonomous stage-structured single-species dynamics system is established in which the individual members of the population have a life history of three stages,immature,mature and old.It is shown that the system is permanent under some appropriate conditions,sufficient conditions are obtained for the global stability of periodic solution of this population dynamical system.
