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 ...

Bifurcation Analysis of a Lotka-Volterra Mutualistic System with Multiple Delays

Abstract and Applied Analysis, 2014
A class of Lotka-Volterra mutualistic system with time delays of benefit and feedback delays is introduced. By analyzing the associated characteristic equation, the local stability of the positive equilibrium and existence of Hopf bifurcation are ...

Hopf bifurcation, stability switches and chaos in a prey-predator system with three stage structure and two time delays

Mathematical Biosciences and Engineering, 2019
A three stage-structured prey-predator model with digestion delay and density dependent delay for the predator is investigated. The stability of the equilibrium point and the Hopf bifurcation of the system by choosing time delay as a bifurcation ...

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.
