Bifurcations and chaos in a novel discrete economic system
Advances 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.

Advances in Difference Equations, 2020 In this paper, a two-species competitive model with Michaelis–Menten type harvesting in the first species is studied. We have made a detailed mathematical analysis of the model to describe some important results that may be produced by the interaction of

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.This research introduces a fractional‐order nonlinear model for the dynamics of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) using Caputo‐type derivatives of noninteger order. Solution properties of the model are investigated by analyzing positivity and boundedness characteristics via the generalized mean value ...

Bifurcation from a normally degenerate manifold
, 2010 Local bifurcation theory typically deals with the response of a degenerate but isolated equilibrium state or periodic orbit of a dynamical system to perturbations controlled by one or more independent parameters, and characteristically uses tools from ...

Difference equations as models of evolutionary population dynamics
Journal of Biological Dynamics, 2019 We describe the evolutionary game theoretic methodology for extending a difference equation population dynamic model in a way so as to account for the Darwinian evolution of model coefficients.

Non-autonomous bifurcation in impulsive systems
Electronic Journal of Qualitative Theory of Differential Equations, 2013 This is the first paper which considers non-autonomous bifurcations in impulsive differential equations. Impulsive generalizations of the non-autonomous pitchfork and transcritical bifurcation are discussed. We consider scalar differential equation with

Impact of Hunting Cooperation and Fear Effect on a Tritrophic Food Chain Model
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.Considering the importance of food chains in the environment from both biological and economic points of view, the life of a living organism depends on the existence of organisms that precede it. Many predators have also developed their own methods of obtaining food, although there is competition among them. Thus, studying hunting cooperation, which is

Bifurcation of Fredholm maps II; The dimension of the set of bifurcation points [PDF]
, 2011 We obtain an estimate for the covering dimension of the set of bifurcation points for solutions of nonlinear elliptic boundary value problems from the principal symbol of the linearization along the trivial branch of ...

Bifurcation diagrams with zero and small positive bacterial influx.
, 2013 Bifurcation curves for Infx = are shown in black, magenta and green, respectively. When Infx , the bifurcation curves are shifted to the right. (a) Type I: the zero Infx transcritical bifurcation point at disappears when .
