【摘要】 根据平面 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.更多还原

【Abstract】 In this paper,the generalized Lotka-Voltcrra model is extended,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 biomathematics.更多还原
