Flip and Neimark–Sacker Bifurcations in a Coupled Logistic Map System [PDF]
Discrete Dynamics in Nature and Society, 2020 In this paper, we consider a system of strongly coupled logistic maps involving two parameters. We classify and investigate the stability of its fixed points. A local bifurcation analysis of the system using center manifold theory is undertaken and then supported by numerical computations.

The existence of Neimark-Sacker bifurcation on a discrete-time SIS-Epidemic model incorporating logistic growth and allee effect [PDF]
Jambura Journal of Biomathematics (JJBM), 2022 This article investigates the dynamical properties of a discrete time SIS-Epidemic model incorporating logistic growth rate and Allee effect. The forward Euler discretization method is employed to obtain the discrete-time model. All possible fixed points

Functional Shift-Induced Degenerate Transcritical Neimark-Sacker Bifurcation in a Discrete Hypercycle [PDF]
International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2023 In this paper, we investigate the impact of functional shifts in a time-discrete cross-catalytic system. We use the hypercycle model considering that one of the species shifts from a cooperator to a degrader.

, 2021 +e dynamics behavior of a discrete-time three-species food chain model is investigated. By using bifurcation theory, it is shown that the equilibrium point of the system loses its stability, and the system undergoes Neimark–Sacker bifurcation, which ...

Neimark–Sacker bifurcation of a chemotherapy treatment of glioblastoma multiform (GBM) [PDF]
Advances in Difference Equations, 2019 Abstract In this paper, we propose a system of differential equations with piecewise constant arguments to describe the growth of GBM under chemotherapeutic treatment and the interaction among the glial cells, the cancer cells, and the chemotherapeutic agents. In this work, the cancer cells are considered as two populations: the sensitive

Invariant Sets, Global Dynamics, and the Neimark-Sacker Bifurcation in the Evolutionary Ricker Model
SymmetryIn this paper, we study the local, global, and bifurcation properties of a planar nonlinear asymmetric discrete model of Ricker type that is derived from a Darwinian evolution strategy based on evolutionary game theory.

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

Dynamics of a Prey-Predator System with Harvesting Effect on Prey
Chaos Theory and Applications, 2022 This article is about the dynamic behavior of a prey-predator model exposed to the harvesting effect on prey. Firstly, the existence and stability of the fixed points of the model are obtained, and then the presence and direction of Neimark-Sacker ...
