摘要
本文讨论了一类生态模型的有效性,种群不灭性,闭轨和同窗轨的存在性,平衡点的稳定性,并定义了向量场同胚映射。
This paper discusses a class of biological models. The availability of models, the persistence of populations, the stability of equilibria and the existence of closed orbits and homoclinic orbits are verified under certain assumptions. A vector field homeomorphism is defined.
