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

Neimark-Sacker Bifurcation of a Third Order Difference Equation
Fundamental 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.

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

The Bifurcation of Two Invariant Closed Curves in a Discrete Model
Discrete 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,
