Bogdanov–Takens and triple zero bifurcations in general differential systems with m delays

open access: yesNonlinear Analysis: Modelling and Control, 2016
This paper mainly concerns the derivation of the normal forms of the Bogdanov–Takens (BT) and triple zero bifurcations for differential systems with m discrete delays. The feasible algorithms to determine the existence of the corresponding bifurcations of the system at the origin are given. By using center manifold reduction and normal form theory, the

Bogdanov-Takens Bifurcation of a Delayed Ratio-Dependent Holling-Tanner Predator Prey System

open access: yesAbstract and Applied Analysis, 2013
A delayed predator prey system with refuge and constant rate harvesting is discussed by applying the normal form theory of retarded functional differential equations introduced by Faria and Magalhães.

The Influence of Generalist Predator and Michaelis–Menten Harvesting in a Holling–Tanner Model

open access: yesAxioms
In this paper, a Holling–Tanner predator–prey model with generalist predators and Michaelis–Menten-type prey harvesting is investigated. We analyze the existence and stability of equilibria and find the system has at most three positive equilibria.

An efficient solution procedure for solving higher-codimension Hopf and Bogdanov–Takens bifurcations

open access: yesCommunications in Nonlinear Science and Numerical Simulation
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 of a state-dependent delay-differential equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
We present a detailed study of a scalar differential equation with threshold state-dependent delayed feedback. This equation arises as a simplification of a gene regulatory model.
