Bogdanov-Takens singularity of a neural network model with delay
In this article, we study Bogdanov-Takens (BT) singularity of a tree-neuron model with time delay. By using the frameworks of Campbell-Yuan [2] and Faria-Magalhaes [4,5], the normal form on the center manifold is derived for this singularity and hence

Complete Hopf and Bogdanov-Takens Bifurcation Analysis on Two Epidemic Models [PDF]
Infectious diseases are a global problem that harms people’s health and well-being and severely threatens human survival. As an epidemiological model, the SIR model is commonly referred to as forecasting how illnesses will spread, how many people will become sick, and how long an epidemic will last. It is also possible to estimate other epidemiological

Bifurcation Analysis of a Generalist Predator-Prey Model with Holling Type II Harvesting
In this paper, we consider a generalist predator–prey model with nonlinear harvesting, which has at most eight non-negative equilibria. We prove that the double positive equilibrium is a cusp of codimension up to 3; therefore, the system exhibits a cusp ...

An efficient solution procedure for solving higher-codimension Hopf and Bogdanov–Takens bifurcations
In solving real world systems for higher-codimension bifurcation problems, one often faces the difficulty in computing the normal form or the focus values associated with generalized Hopf bifurcation, and the normal form with unfolding for higher-codimension Bogdanov-Takens bifurcation.

Dynamics near manifolds of equilibria of codimension one and bifurcation without parameters
We investigate the breakdown of normal hyperbolicity of a manifold of equilibria of a flow. In contrast to classical bifurcation theory we assume the absence of any flow-invariant foliation at the singularity transverse to the manifold of equilibria.

Semi-global analysis of periodic and quasi-periodic k:1 and k:2 resonances [PDF]
The present paper investigates a family of nonlinear oscillators at Hopf bifurcation, driven by a small quasi-periodic forcing. In particular, we are interested in the situation that at bifurcation and for vanishing forcing strength, the driving ...
