Influence of time delay on bifurcation of a synthetic drug transmission model with psychological addicts

open access: yesAdvances in Difference Equations, 2020
A synthetic drug transmission model with psychological addicts and time delay is proposed in this paper. By analyzing the corresponding characteristic equation and choosing the time delay as the bifurcation parameter, a set of sufficient criteria ...

Introduction to bifurcation theory [PDF]

open access: yesReviews of Modern Physics, 1991
The theory of bifurcation from equilibria based on center-manifold reduction and Poincar\'e-Birkhoff normal forms is reviewed at an introductory level. Both differential equations and maps are discussed, and recent results explaining the symmetry of the normal form are derived.

On the torus bifurcation in averaging theory [PDF]

open access: yesJournal of Differential Equations, 2020
In this paper, we take advantage of the averaging theory to investigate a torus bifurcation in two-parameter families of 2D nonautonomous differential equations. Our strategy consists in looking for generic conditions on the averaged functions that ensure the existence of a curve in the parameter space characterized by a Neimark-Sacker bifurcation in ...

Analysis on recurrence behavior in oscillating networks of biologically relevant organic reactions

open access: yesMathematical Biosciences and Engineering, 2019
In this paper, we present a new method based on dynamical system theory to study certain type of slow-fast motions in dynamical systems, for which geometric singular perturbation theory may not be applicable.
