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

IEEE 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 ...

International Journal of Differential Equations, Volume 2024, Issue 1, 2024.In the present article, the matrix projective synchronization (MPS) and the inverse matrix projective synchronization (IMPS) have been analyzed with fractional‐order chaotic systems with uncertain terms. First, we theoretically discussed both types of synchronizations.

Estudo da bifurcação de Neimark-Sacker [PDF]
This dissertation deals with a local bifurcation for planar smooth mappings, depending on a real parameter, called Neimark-Sacker bifurcation of codimension 1, which, in a certain sense, shares many similarities with the Hopf bifurcation for ordinary ...

, 2015 A discrete-time model is presented to describe the complex interaction between industrial production and environmental quality in a closed area. Its Neimark–Sacker bifurcation and chaos are discussed based on Wen’s explicit Neimark–Sacker bifurcation ...

Flip and Neimark–Sacker Bifurcations in a Coupled Logistic Map System
, 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.

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

Investigating Global Stability and Bifurcation in an Ecological Dynamical System
Complexity, Volume 2024, Issue 1, 2024.We consider a continuous‐time model describing the interaction between phytoplankton and zooplankton using a Holling type‐II response. We then transform this continuous‐time model into a discrete‐time counterpart using a fractional‐order discretization method.

Consumer sentiment and business cycles: a Neimark-Sacker bifurcation scenario
We seek to demonstrate that consumer sentiment may create fluctuations in economic activity. Our nonlinear discrete-time model possesses, for instance, a Neimark-Sacker bifurcation, after which a stable steady state is replaced by (quasi-)periodic motion.

, 2022 In this paper, a discrete predator-prey model with Allee effect which is obtained by the forward Euler method has been investigated. The local stability conditions of the model at the fixed point have been discussed.
