Global Hopf Bifurcation on a Plankton Model with Time Delay
Based on the global Hopf bifurcation theory of general functional differential equations es-tablished by Wu Jianhong and others,this paper studies the stability of three-dimensional floating delay model and the global existence of Hopf bifurcation with time lag as parameters.The correctness of theo-retical analysis is verified by numerical simulation,and it is concluded that the input rate of nutrients greatly affects the period of periodic solutions.
