Bifurcation and chaos in a discrete predator-prey system of Leslie type with Michaelis-Menten prey harvesting

open access: yesOpen Mathematics, 2022
In this paper, a discrete Leslie-Gower predator-prey system with Michaelis-Menten type harvesting is studied. Conditions on the existence and stability of fixed points are obtained.

Stability and Cycles in a Cobweb Model with Heterogeneous Expectations [PDF]

open access: yes
We investigate the dynamics of a cobweb model with heterogeneous beliefs, generalizing the example of Brock and Hommes (1997). We examine situations where the agents form expectations by using either rational expectations, or a type of adaptive ...

Bifurcations and chaos in a novel discrete economic system

open access: yesAdvances in Mechanical Engineering, 2019
In this article, a novel discrete system based on an economic model is introduced. Conditions for local stability of the model’s fixed points are obtained. Existence of supercritical Neimark–Sacker bifurcation is shown around the game’s Nash equilibrium.

Using Shannon Entropy and Contagion Index to Interpret Pattern Self-Organization in a Dynamic Vegetation-Sand Model

open access: yesIEEE Access, 2020
Vegetation pattern is one of the most important self-organized patterns in ecological systems. The formation mechanism of vegetation patterns has been attributed to dynamic bifurcations, while from the external perspective, the regularity of patterns ...

Study on the Compatibility of Multi-Bifurcations by Simulations of Pattern Formation

open access: yesIEEE Access, 2019
Bifurcation is considered the main mathematical mechanism for the formation of spatial self-organizing patterns in many studies. When bifurcation was initially defined, only the transition of the system from stable state to unstable state or from uniform

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

open access: yesJournal 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

open access: yesDiscrete 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

open access: yesIEEE 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

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.
