Global hopf bifurcation
WebMay 25, 2024 · Especially, we examine the onset and termination of Hopf bifurcations of periodic solutions from the unique positive equilibrium. We locate all of the stability switches for the equilibrium and demonstrate that the global Hopf bifurcation branches are bounded. This result implies the system undergoes oscillatory behavior only with … WebIn this article, we studied global stability and Hopf bifurcation of a newly delayed cooperative species model with density-dependent diffusion. When τ = 0 , we investigated the persistence properties in the case of self-diffusion and global stability of positive equilibrium by constructing Lyapunov function, see Fig. 2 , Fig. 3 , Fig. 4 , Fig ...
