, 2013 Necessary and sufficient conditions are obtained for an ambiskew polynomial algebra A over a Hopf k-algebra R to possess the structure of a Hopf algebra extending that of R, in which the added variables X+ and X- are skew primitive.

AxiomsThis paper mainly studies the equivariant Hopf bifurcation of a delayed reaction–diffusion predator–prey model with stage structures on a two-dimensional circular domain. Firstly, we calculate the existence of steady-state solutions, and then analyze the

Bifurcation of a Microelectromechanical Nonlinear Coupling System with Delay Feedback
Journal of Applied Mathematics, 2014 The dynamics of a kind of electromechanical coupling deformable micromirror device torsion micromirror with delay are investigated. Based on the distribution of eigenvalues, we prove that a sequence of Hopf bifurcation occurs at the equilibrium as the ...

Existence of Bifurcation in Macroeconomic Dynamics: Grandmont was Right [PDF]
Grandmont (1985) found that the parameter space of the most classical dynamic general-equilibrium macroeconomic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic ...

Hopf bifurcations for a delayed discrete single population patch model in advective environments
European Journal of Applied MathematicsIn this paper, we consider a delayed discrete single population patch model in advective environments. The individuals are subject to both random and directed movements, and there is a net loss of individuals at the downstream end due to the flow into a ...

Bifurcation analysis of surge and rotating stall in the Moore-Greitzer compression system [PDF]
, 2002 A simple compression system model, described by a set of three ordinary nonlinear differential equations (the Moore-Greitzer model) is studied using bifurcation analysis to give a qualitative understanding of the presence of surge and rotating stall ...

Periodic orbits for an autonomous version of the Duffing–Holmes oscillator
Nonlinear AnalysisIn the autonomous Duffing–Holmes oscillator, the existence of periodic orbits was detected numerically. Using the Hopf bifurcation theory, we prove analytically that such periodic orbits exist.
