Bifurcation analysis of a discrete SIS model with bilinear incidence depending on new infection
Mathematical Biosciences and Engineering, 2013 A discrete SIS epidemic model with the bilinear incidence depending on the new infection is formulated and studied.The condition for the global stability of the disease free equilibrium is obtained.The existence of the endemic equilibrium and its ...

The Non-Autonomous Saddle Node Bifurcation
Journal of Computational MathemticaThis work explores the phenomenon of saddle-node bifurcation in both autonomous and non-autonomous dynamical systems. The classical autonomous case is illustrated through a simple differential equation that demonstrates the creation and annihilation of fixed points as a system parameter varies.

Intermittency and Jakobson's theorem near saddle-node bifurcations
Discrete & Continuous Dynamical Systems - A, 2007 We discuss one parameter families of unimodal maps, with negative Schwarzian derivative, unfolding a saddle-node bifurcation. We show that there is a parameter set of positive but not full Lebesgue density at the bifurcation, for which the maps exhibit absolutely continuous invariant measures which are supported on the largest possible interval.

Bifurcation in a Leslie–Gower system with fear in predators and strong Allee effect in prey
Nonlinear AnalysisIn this paper, we consider a modified Leslie–Gower predator–prey model with Allee effect on prey and fear effect on predators. Results show complex dynamical behaviors in the model with these factors.

Chaos in driven Alfvén systems: unstable periodic orbits and chaotic saddles [PDF]
Nonlinear Processes in Geophysics, 2007 The chaotic dynamics of Alfvén waves in space plasmas governed by the derivative nonlinear Schrödinger equation, in the low-dimensional limit described by stationary spatial solutions, is studied.

Complex Dynamics in a Singular Delayed Bioeconomic Model with and without Stochastic Fluctuation
Discrete Dynamics in Nature and Society, 2015 A singular delayed biological economic predator-prey system with and without stochastic fluctuation is proposed. The conditions of singularity induced bifurcation are gained, and a state feedback controller is designed to eliminate such bifurcation ...
