ON THE SUPERCRITICALITY OF THE FIRST HOPF BIFURCATION IN A DELAY BOUNDARY PROBLEM
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
The goal of this paper is to analyze the character of the first Hopf bifurcation (subcritical versus supercritical) that appears in a one-dimensional reaction-diffusion equation with nonlinear boundary conditions of logistic ...
On the appearance of a Hopf bifurcation in a non-ideal mechanical problem

Non-resonant double Hopf bifurcations: The complex case
(Academic Press Ltd - Elsevier Science Ltd, 2009-04-24)
The analysis of the unfolding of a non-resonant double Hopf singularity is considered using the frequency domain and the normal form methodologies. A higher-order harmonic balance and the evaluation of Floquet multipliers ...
Stability of small-amplitude periodic solutions near Hopf bifurcations in time-delayed fully-connected PLL networks
(Elsevier B.V., 2017-04-01)
In this paper we investigate stability conditions for small-amplitude periodic solutions emerging near symmetry-preserving Hopf bifurcations in a time-delayed fully-connected N-node PLL network. The study of this type of ...
Zero-Hopf Bifurcations in Three-Dimensional Chaotic Systems with One Stable Equilibrium
(2020-10-01)
In [Molaie et al., 2013] the authors provided the expressions of 23 quadratic differential systems in R3 with the unusual feature of having chaotic dynamics coexisting with one stable equilibrium point. In this paper, we ...

Hopf Bifurcation Analysis of Distributed Delay Equations with Applications to Neural Networks
(World Scientific, 2015-11)
In this paper, we study how to capture smooth oscillations arising from delay-differential equations with distributed delays. For this purpose, we introduce a modified version of the frequency-domain method based on the ...
A simple electronic device to experiment with the Hopf bifurcation
(Sociedad Mexicana de Física, 2019-01)
We present a simple low-cost electronic circuit that is able to show two different dynamical regimens with oscillations of voltages and with constant values of them. This device is designed as a negative feedback three-node ...
