Transcritical bifurcation of an immunosuppressive infection model [PDF]

open access: greenIranian Journal of Numerical Analysis and Optimization, 2016
In this paper, the dynamic behavior of an immunosuppressive infection model, speci_cally AIDS, is analyzed. We show through a simple mathematical model that a sigmoidal CTL response can lead to the occurrence of transcritical bifurcation.

Transcritical bifurcation in a multiparametric nonlinear system

open access: goldAIMS Mathematics, 2022
In this paper we study a multiparametric nonlinear system with a transcritical bifurcation in a region of points of $ \mathbb{R}^3 $. The parametric regions that constitute the boundaries where important qualitative changes occur in the dynamics of the ...

A note on the direction of the transcritical bifurcation in epidemic models

open access: diamondNonlinear Analysis, 2015
In classical epidemic models, it is common to observe that a disease-free equilibrium looses its stability for R0=1 and a transcritical bifurcation takes place.

A sequence of transcritical bifurcations in a suspension of gyrotactic microswimmers in vertical pipe [PDF]

open access: green, 2020
Kessler (Nature, vol. 313, 1985, pp. 218-220) first showed that plume-like structures spontaneously appear from both stationary and flowing suspensions of gyrotactic microswimmers in a vertical pipe.

Discretizing the transcritical and pitchfork bifurcations -- conjugacy\n results [PDF]

open access: greenJournal of Difference Equations and Applications, 2014
We present two case studies in one-dimensional dynamics concerning the discretization of transcritical (TC) and pitchfork (PF) bifurcations. In the vicinity of a TC or PF bifurcation point and under some natural assumptions on the one-step discretization method of order $p\ge 1$, we show that the time-$h$ exact and the step-size-$h$ discretized ...

Transcritical Bifurcation without Parameters in Memristive Circuits [PDF]

open access: greenSIAM Journal on Applied Mathematics, 2018
The transcritical bifurcation without parameters (TBWP) describes a stability change along a line of equilibria, resulting from the loss of normal hyperbolicity at a given point of such a line. Memristive circuits systematically yield manifolds of non-isolated equilibria, and in this paper we address a systematic characterization of the TBWP in ...

Transcritical Bifurcations and Algebraic Aspects of Quadratic Multiparametric Families

open access: diamondWSEAS TRANSACTIONS ON MATHEMATICS, 2021
This article reveals an analysis of the quadratic systems that hold multiparametric families therefore, in the first instance the quadratic systems are identified and classified in order to facilitate their study and then the stability of the critical points in the finite plane, its bifurcations, stable manifold and lastly, the stability of the ...

Transcritical Bifurcation for the Conditional Distribution of a Diffusion Process [PDF]

open access: greenJournal of Theoretical Probability, 2022
In this article, we describe a simple class of models of absorbed diffusion processes with parameter, whose conditional law exhibits a transcritical bifurcation. Our proofs are based on the description of the set of quasi-stationary distributions for general two-clusters reducible processes.
