Proportional relations between the wave number and amplitude of spiral waves near Neimark-Sacker bifurcations

The spatiotemporal distribution patterns of interacting populations are broadly accepted as a pivotal factor in sustaining species diversity.

Stability and bifurcation analysis for a discrete-time bidirectional ring neural network model with delay

Electronic Journal of Differential Equations, 2013
We study a class of discrete-time bidirectional ring neural network model with delay. We discuss the asymptotic stability of the origin and the existence of Neimark-Sacker bifurcations, by analyzing the corresponding characteristic equation ...

Transcritical Bifurcation and Neimark–Sacker Bifurcation in a Discrete Predator–Prey Model with Constant-Effort Harvesting

This study develops a semi-discretized time system from the continuous-time Rosenzweig–-MacArthur model via the method of piecewise constant argument—a discretization approach that preserves both mathematical rigor and biological interpretability.

ATTRACTORS OF A MODEL OF TWO CONSUMERS NEAR THE NEIMARK-SACKER BIFURCTION [PDF]

, 2019
We study dynamics of the stochastic consumption network nearby Neimark–Sacker bifurcation. The parametric zones of the existence of equilibria, cycles and closed invariant curves are studied.

Chaos Control, Codimension-One and Codimension-Two 1 : 2 Strong Resonance Bifurcation Analysis of a Predator-Prey Model with Holling Types I and III Functional Responses

Complexity
We study the existence of fixed points, local stability analysis, bifurcation sets at fixed points, codimension-one and codimension-two bifurcation analysis, and chaos control in a predator-prey model with Holling types I and III functional responses. It

Codimension-one bifurcation analysis and chaos of a discrete prey–predator system

Journal of Taibah University for Science
In this paper, we explore local dynamics at equilibrium points, the existence of bifurcation sets and codimension-one bifurcation analysis of a discrete prey–predator system with Holling type-II functional response.
