Bifurcation Analysis of a Predator–Prey Model with Coefficient-Dependent Dual Time Delays
MathematicsIn this paper, a class of two-delay predator–prey models with coefficient-dependent delay is studied. It examines the combined effect of fear-induced delay and post-predation biomass conversion delay on the stability of predator–prey systems.

Hopf Bifurcations in a Watt Governor with a Spring
, 2008 This paper pursues the study carried out in [ 10], focusing on the codimension one Hopf bifurcations in the hexagonal Watt governor system. Here are studied Hopf bifurcations of codimensions two, three and four and the pertinent Lyapunov stability ...

Stability of non-parallel flow in a channel
Le Matematiche, 1991 This is a review of several generalizations of Hiemenz's classic solution for steady two-dimensional flow of a uniform incompressible viscous fluid near a stagnation point on a bluff body.

Global Hopf bifurcation and connected components in a delayed predator–prey model
European Journal of Applied MathematicsWe study the dynamics of a delayed predator–prey system with Holling type II functional response, focusing on the interplay between time delay and carrying capacity.

Normal Forms for the Hopf Bifurcations in the Lorenz System
, 2010 In this essay we compute the the twist number for the Hopf bifurcations in the Lorenz equation. This number is the ratio of the real and the imaginary part of the first coefficient of the normal form. Our purpose is to investigate the possibility of rank

FOLD–HOPF BIFURCATIONS OF THE ROSE–HINDMARSH MODEL WITH TIME DELAY
, 2011 In neural processing information, when we consider the finite propagation speed of signals in synapses, a time delay signal self-feedback mechanism is introduced into the well-known Rose–Hindmarsh Model.

Bifurcation Analysis for an OSN Model with Two Delays
MathematicsIn this research, we introduce and analyze a mathematical model for online social networks, incorporating two distinct delays. These delays represent the time it takes for active users within the network to begin disengaging, either with or without ...

Nilpotent Hopf Bifurcations in coupled cell systems
, 2006 Network architecture can lead to robust synchrony in coupled systems and, surprisingly, to codimension one bifurcations from synchronous equilibria at which the associated Jacobian is nilpotent.
