Cournot–Bertrand Duopoly Model: Dynamic Analysis Based on a Computed Cost

Complexity, Volume 2024, Issue 1, 2024.
In this paper, some mathematical properties and dynamic investigations of a Cournot–Bertrand duopoly game using a computed nonlinear cost are studied. The game is repeated and its evolution is presented by noninvertible map. The fixed points for this map are calculated and their stability conditions are discussed.

Global dynamics and bifurcation analysis of a host–parasitoid model with strong Allee effect

Journal of Biological Dynamics, 2017
In this paper, we study the global dynamics and bifurcations of a two-dimensional discrete time host–parasitoid model with strong Allee effect. The existence of fixed points and their stability are analysed in all allowed parametric region.

Neimark-Sacker Bifurcation and Chaos Control in a Fractional-Order Plant-Herbivore Model

Discrete Dynamics in Nature and Society, 2017
This work is related to dynamics of a discrete-time 3-dimensional plant-herbivore model. We investigate existence and uniqueness of positive equilibrium and parametric conditions for local asymptotic stability of positive equilibrium point of this model.

Flip and Neimark-Sacker Bifurcations of a Discrete Time Predator-Pre Model

IEEE Access, 2019
In this paper, we investigate the system undergoes flip and Neimark Sacker bifurcation in the interior of R+2 by using the center manifold theorem and bifurcation theory. The dynamics of this discrete time predator-pre model is investigated in the closed

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.

A simple model of a speculative housing market [PDF]

We develop a simple model of a speculative housing market in which the demand for houses is influenced by expectations about future housing prices. Guided by empirical evidence, agents rely on extrapolative and regressive forecasting rules to form their ...

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.

A Robust Rational Route to in a Simple Asset Pricing Model (revised March 2004) [PDF]

We investigate asset pricing dynamics in an adaptive evolutionary asset pricing model with fundamentalists, trend followers and a market maker. Agents can choose between a fundamentalist strategy at positive information cost or choose a trend following ...

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 ...
