Bogdanov–Takens singularity in the simple memristive time-delay system
, 2019 In this paper, a simple memristive system is considered. We obtain existence of Bogdanov–Takens (B–T) bifurcation at the equilibrium in the 2D memristive time-delay system.

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

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

ANALYSIS OF THE TAKENS–BOGDANOV BIFURCATION ON m-PARAMETERIZED VECTOR FIELDS
, 2010 Given an m-parameterized family of n-dimensional vector fields, such that: (i) for some value of the parameters, the family has an equilibrium point, (ii) its linearization has a double zero eigenvalue and no other eigenvalue on the imaginary axis ...

Análisis de la bifurcación Takens-Bogdanov en el modelo depredador-presa con defensa de grupo
, 2022 El modelo matemático poblacional de tipo Gause de dos poblaciones interactuando una como depredador y la otra como presa, existe desde 1935 y ha sido muy estudiado desde diferentes puntos de vista desde los años 70 del siglo XX hasta nuestros días.

Degenerated Bogdanov-Takens bifurcations in an immuno-tumor model
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2009 A mathematical immuno-tumor model proposed by A. Kavaliauskas [Nonlinear Anal. Model. Control 8, 55 (2003)] and consisting of a Cauchy problem for a system of two first-order ordinary differential equations is studied.

Dynamics of a state-dependent delay-differential equation
Electronic Journal of Qualitative Theory of Differential EquationsWe 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.
