Cluster Oscillation of a Fractional-Order Duffing System with Slow Variable Parameter Excitation

open access: yesFractal and Fractional, 2022
The complicated dynamic behavior of a fractional-order Duffing system with slow variable parameter excitation is investigated. The stability and bifurcation behavior of the fast subsystem are analyzed by using the dynamic theory of fractional-order ...

Exploring the mechanisms of differentiation, dedifferentiation, reprogramming and transdifferentiation. [PDF]

open access: yesPLoS ONE, 2014
We explored the underlying mechanisms of differentiation, dedifferentiation, reprogramming and transdifferentiation (cell type switchings) from landscape and flux perspectives.

Finite-time nonautonomous bifurcation in impulsive systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
The purpose of this article is to investigate nonautonomous bifurcation in impulsive differential equations. The impulsive finite-time analogues of transcritical and pitchfork bifurcation are provided.

The chaotic mechanisms in some jerk systems

open access: yesAIMS Mathematics, 2022
In this work, a five-parameter jerk system with one hyperbolic sine nonlinearity is proposed, in which $ \varepsilon $ is a small parameter, and $ a $, $ b $, $ c $, $ d $ are some other parameters.

Classical bifurcations and entanglement in smooth Hamiltonian system [PDF]

open access: yes, 2007
We study entanglement in two coupled quartic oscillators. It is shown that the entanglement, as measured by the von Neumann entropy, increases with the classical chaos parameter for generic chaotic eigenstates.

Multiple bifurcations and periodic coexistence in a delayed Hopfield two-neural system with a monotonic activation function

open access: yesAdvances in Difference Equations, 2019
In this paper, we consider a delayed Hopfield two-neural system with a monotonic activation function and find the periodic coexistence by bifurcation analysis.

Bifurcation analysis of a two-dimensional discrete Hindmarsh–Rose type model

open access: yesAdvances in Difference Equations, 2019
In this paper, bifurcation analysis of a discrete Hindmarsh–Rose model is carried out in the plane. This paper shows that the model undergoes a flip bifurcation, a Neimark–Sacker bifurcation, and 1:2 $1:2$ resonance which includes a pitchfork bifurcation,

Bifurcation Theory for SPDEs: Finite-time Lyapunov Exponents and Amplitude Equations [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2023
We consider a stochastic partial differential equation close to bifurcation of pitchfork type, where a one-dimensional space changes its stability. For finite-time Lyapunov exponents we characterize regions depending on the distance from bifurcation and ...

Coalescence of limit cycles in the presence of noise [PDF]

open access: yes, 2023
Complex dynamical systems may exhibit multiple steady states, including time-periodic limit cycles, where the final trajectory depends on initial conditions. With tuning of parameters, limit cycles can proliferate or merge at an exceptional point. Here we ask how dynamics in the vicinity of such a bifurcation are influenced by noise.
