Bifurcation analysis of an SIS model with a modified nonlinear incidence rate

open access: yesElectronic Research Archive
A modified nonlinear incidence rate in an SIS epidemic model was investigated. When a new disease emerged or an old one resurged, the infectivity was initially high. Subsequently, the psychological effect attenuated the infectivity.

Bifurcation Behavior Analysis in a Predator-Prey Model

open access: yesDiscrete Dynamics in Nature and Society, 2016
A predator-prey model is studied mathematically and numerically. The aim is to explore how some key factors influence dynamic evolutionary mechanism of steady conversion and bifurcation behavior in predator-prey model.

Stability of non-parallel flow in a channel

open access: yesLe Matematiche, 1991
This is a review of several generalizations of Hiemenz's classic solution for steady two-dimensional flow of a uniform incompressible viscous fluid near a stagnation point on a bluff body.

The Bogdanov–Takens Normal Form: A Minimal Model for Single Neuron Dynamics

open access: yesEntropy, 2015
Conductance-based (CB) models are a class of high dimensional dynamical systems derived from biophysical principles to describe in detail the electrical dynamics of single neurons.

Dynamic behaviors of a Leslie-Gower predator-prey model with Smith growth and constant-yield harvesting

open access: yesElectronic Research Archive
A Leslie-Gower predator-prey model with Smith growth and constant-yield harvesting is proposed in this paper. We show that the system admits at most two boundary equilibria, both of which are unstable. The degenerate positive equilibrium of the system is

Dynamics of a Predator-Prey System with a Mate-Finding Allee Effect

open access: yesAbstract and Applied Analysis, 2014
We consider a ratio-dependent predator-prey system with a mate-finding Allee effect on prey. The stability properties of the equilibria and a complete bifurcation analysis, including the existence of a saddle-node, a Hopf bifurcation, and, a Bogdanov ...

Bifurcations of a modified Leslie–Gower predator–prey model with fear, Allee effect and hunting cooperation strategy

open access: yesJournal of Biological Dynamics
The fear preoften leads to changes in the physiological characteristics of the prey. Different stages of prey exhibit different physiological behaviours, such as susceptibility to predator risk, which often leads to Allee effect.
