Bifurcations associated with a three-fold zero eigenvalue [PDF]

open access: yesQuarterly of Applied Mathematics, 1988
The bifurcation and instability behavior of a nonlinear autonomous system in the vicinity of a compound critical point is studied in detail. The critical point is characterized by a triple zero of index one eigenvalue, and the system is described by three independent parameters.

Codimension-Two Bifurcations of a Simplified Discrete-Time SIR Model with Nonlinear Incidence and Recovery Rates

open access: yesMathematics, 2023
In this paper, a simplified discrete-time SIR model with nonlinear incidence and recovery rates is discussed. Here, using the integral step size and the intervention level as control parameters, we mainly discuss three types of codimension-two ...

The generic unfolding of a codimension-two connection to a two-fold singularity of planar Filippov systems

open access: yes, 2017
Generic bifurcation theory was classically well developed for smooth differential systems, establishing results for $k$-parameter families of planar vector fields.

Limit Cycles Bifurcating from an Invisible Fold–Fold in Planar Piecewise Hamiltonian Systems

open access: yesJournal of Dynamical and Control Systems, 2020
The paper deals with piecewise differential systems and the existence of limit cycles which bifurcates from an invisible fold-fold at the origin after some perturbation. The authors state three main results which give conditions for, given an integer \(k\), there exist exactly \(k\) hyperbolic crossing limit cycles in a suitable neighborhood of the ...

Predicting discrete-time bifurcations with deep learning

open access: yesNature Communications, 2023
Many natural and man-made systems are prone to critical transitions—abrupt and potentially devastating changes in dynamics. Deep learning classifiers can provide an early warning signal for critical transitions by learning generic features of ...

Numerical Bifurcation Analysis of Conformal Formulations of the Einstein Constraints

open access: yes, 2011
The Einstein constraint equations have been the subject of study for more than fifty years. The introduction of the conformal method in the 1970's as a parameterization of initial data for the Einstein equations led to increased interest in the ...
