摘要
据平面 C^2-动态系统平衡态的几何定性新法,推广一类广义 Lotka-Volterra 模型,作出一个不存在极限环的参考类,为创建常微模型生物数学定性制图学的需要,开展涉及该类型模型定性制图新法的研究.
In this paper,we extend the generalized Lotka-Volterra model with a set of sufficient conditions to a comparison type of reference class of trajectories,in which no limiting cycles exist.It will be used for the work in the fascinating qualitative nomography of the ordinary differential models in biomathe matics.
