Neimark-sacker bifurcations near degenerate grazing point in a two degree-of-freedom impact oscillator

open access: yes, 2018
© 2019 by ASME. Saddle-node or period-doubling bifurcations of the near-grazing impact periodic motions have been extensively studied in the impact oscillators, but the near-grazing Neimark-Sacker bifurcations have not been discussed yet.

Consumer sentiment and business cycles: a Neimark-Sacker bifurcation scenario

open access: yes
We seek to demonstrate that consumer sentiment may create fluctuations in economic activity. Our nonlinear discrete-time model possesses, for instance, a Neimark-Sacker bifurcation, after which a stable steady state is replaced by (quasi-)periodic motion.

Stability and bifurcation analysis in a host–parasitoid model with Hassell growth function

open access: yesAdvances in Difference Equations, 2018
In this paper, a discrete-time host–parasitoid model with Hassell growth function for the host is considered. The sufficient conditions for the existence of the equilibrium points are obtained and a local stability analysis of the model is performed.

Dynamics of a Discrete Internet Congestion Control Model

open access: yesDiscrete Dynamics in Nature and Society, 2011
We consider a discrete Internet model with a single link accessed by a single source, which responds to congestion signals from the network. Firstly, the stability of the equilibria of the system is investigated by analyzing the characteristic equation ...

Neimark-Sacker Bifurcation of a Third Order Difference Equation

open access: yesFundamental Journal of Mathematics and Applications, 2019
In this paper, we investigate the bifurcation of a third order rational difference equation. Firstly, we show that the equation undergoes a Neimark-Sacker bifurcation when the parameter reaches a critical value. Then, we consider the direction of the Neimark-Sacker bifurcation. Finally, we give some numerical simulations of our results.

Neimark-Sacker bifurcation for the discrete-delay Kaldor model [PDF]

open access: yes
We consider a discrete-delay time, Kaldor non-linear business cycle model in income and capital. Given an investment function, resembling the one discussed by Rodano, we use the linear approximation analysis to state the local stability property and ...

The Bifurcation of Two Invariant Closed Curves in a Discrete Model

open access: yesDiscrete Dynamics in Nature and Society, 2018
A discrete population model integrated using the forward Euler method is investigated. The qualitative bifurcation analysis indicates that the model exhibits rich dynamical behaviors including the existence of the equilibrium state, the flip bifurcation,
