Bifurcation Analysis for a Two-Dimensional Discrete-Time Hopfield Neural Network with Delays

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
A bifurcation analysis is undertaken for a discrete-time Hopfield neural network with four delays. Conditions ensuring the asymptotic stability of the null solution are obtained with respect to two parameters of the system.

Calculation of coefficients of simplest normal forms of Neimark-Sacker and generalized Neimark-Sacker bifurcations

open access: yesJournal of Physics: Conference Series, 2008
The coefficients of the simplest normal forms of both high-dimensional Neimark-Sacker and generalized Neimark-Sacker bifurcation systems were discussed. On the basis of the simplest normal form theory, using appropriate nonlinear transformations, direct computation and the second complete induction, the central manifold equations were further reduced ...

Dynamic Behavior and Bifurcation Analysis of a Difference Equation Including Exponential Terms

open access: yesPan-American Journal of Mathematics
In this paper, the local stability, the boundedness, rate of convergence and the conditions of Neimark-Sacker bifurcation concerning difference equation xn+1=α1xn+α2xn-1+β1xnexp(-x2n-1)+β2xn-1exp(-x2n-1), n=0,1, ..., are investigated.

Neimark–Sacker bifurcation and stability analysis of a discrete-time prey–predator model with Allee effect in prey

open access: yesAdvances in Difference Equations, 2019
In this paper, the dynamical behaviors of a discrete-time prey–predator model with Allee effect on the prey population are investigated. The existence and topological classification of the fixed points of the model are analyzed.

Coexisting patterns of population oscillations: the degenerate Neimark Sacker bifurcation as a generic mechanism

open access: yes, 2010
We investigate a population dynamics model that exhibits a Neimark Sacker bifurcation with a period that is naturally close to 4. Beyond the bifurcation, the period becomes soon locked at 4 due to a strong resonance, and a second attractor of period 2 ...

Analyzing Predator-Prey Interaction in Chaotic and Bifurcating Environments

open access: yesChaos Theory and Applications, 2023
An analysis of discrete-time predator-prey systems is presented in this paper by determining the minimum amount of prey consumed before predators reproduce, as well as by analyzing the system's stability and bifurcation. In order to investigate the local

Stability and Bifurcation Analysis of a Nonlinear Discrete Logistic Model with Delay

open access: yesDiscrete Dynamics in Nature and Society, 2013
We consider a nonlinear discrete logistic model with delay. The characteristic equation of the linearized system at the positive equilibrium is a polynomial equation involving high order terms.

Torsional solutions of convection in rotating fluid spheres [PDF]

open access: yes, 2019
A numerical study of the nonlinear torsional solutions of convection in rotating, internally heated, self-gravitating fluid spheres is presented. Their dependence on the Rayleigh number has been found for two pairs of Ekman (E) and small Prandtl (Pr ...
