具多时滞合作系统的稳定性与 Hopf 分支
Stability and Hopf Bifurcation of a Cooperative System with Multiple Time Delays
摘要
Abstract
For a class of cooperative systems with three discrete time delays,with two combinations of three time delays τ1 ,τ2 ,τ as bifurcation parameters, based on the analysis of the root of the characteristic equation and the standard theory,we investigated the stability of equilibrium points and the sufficient conditions of local Hopf bifurcation in two cases,and obtained the algorithms and calculation formulas for determining the stability and bifurcation direction of the bifurcation periodic solutions.We gave the theoretical proof of the existence of global Hopf bifurcation,and the existence of bifurcation periodic solutions from local to global can be verified by numerical simulations.关键词
