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 ...

Hopf bifurcations for a delayed discrete single population patch model in advective environments

European Journal of Applied Mathematics
In 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 ...

Periodic orbits for an autonomous version of the Duffing–Holmes oscillator

Nonlinear Analysis
In 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.
