Dynamics and Global Bifurcations in Two Symmetrically Coupled Non-Invertible Maps
Mathematics, 2023 The theory of critical curves determines the main characteristics of a discrete dynamical system in two dimensions. One important property that has garnered recent attention is the problem of chaos synchronization, along with the location of its chaotic ...

Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow [PDF]
Journal of Fluid Mechanics, 2013 Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional nonlinear magnetohydrodynamic process, the study of which is relevant to the understanding of accretion processes and magnetic field generation in astrophysics.

Filippov Ratio-Dependent Prey-Predator Model with Threshold Policy Control
Abstract and Applied Analysis, 2013 The Filippov ratio-dependent prey-predator model with economic threshold is proposed and studied. In particular, the sliding mode domain, sliding mode dynamics, and the existence of four types of equilibria and tangent points are investigated firstly ...

Streamline topologies and their bifurcations for mixed convective peristaltic flow
AIP Advances, 2015 In this work our focus is on streamlines patterns and their bifurcations for mixed convective peristaltic flow of Newtonian fluid with heat transfer. The flow is considered in a two dimensional symmetric channel and the governing equations are simplified

Bifurcation Analysis in a Two-Dimensional Neutral Differential Equation
Abstract and Applied Analysis, 2013 The dynamics of a 2-dimensional neural network model in neutral form are investigated. We prove that a sequence of Hopf bifurcations occurs at the origin as the delay increases.

Global Hopf Bifurcation Analysis for a Time-Delayed Model of Asset Prices
Discrete Dynamics in Nature and Society, 2010 A time-delayed model of speculative asset markets is investigated to discuss the effect of time delay and market fraction of the fundamentalists on the dynamics of asset prices.

, 2016 In this paper we study the Sotomayor-Teixeira regularization of a general visible fold singularity of a planar Filippov system. Extending Geometric Fenichel Theory beyond the fold with asymptotic methods, we determine the deviation of the orbits of the

Local versus global stability in dynamical systems with consecutive Hopf bifurcations
Physical Review Research, 2023 Quantifying the stability of an equilibrium is central in the theory of dynamical systems as well as in engineering and control. A comprehensive picture must include the response to both small and large perturbations, leading to the concepts of local ...
