摘要
讨论一类总数依赖非线性年龄结构种群模型的动力特性,给出了系统的一个等价问题,并讨论了系统的平衡解和非平衡解,得到了平衡解和非平衡解存在的充要条件.
This paper studies the dynamical behavior of a class of total size dependent nonlinear age-structured population model. We give the problem of equal value for the system, and discuss the non-equilibrium solution and equilibrium solution of system. We obtained the necessary and sufficient conditions for there exists the non-equilibrium solution and equilibrium solution of system.
