【Abstract】 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.更多还原
