Heteroclinic Bifurcation Behaviors of a Duffing Oscillator with Delayed Feedback [PDF]

open access: goldShock and Vibration, 2018
The heteroclinic bifurcation and chaos of a Duffing oscillator with forcing excitation under both delayed displacement feedback and delayed velocity feedback are studied by Melnikov method.

Heteroclinic bifurcation for a general predator-prey model with Allee effect and state feedback impulsive control strategy

open access: goldMathematical Biosciences and Engineering, 2015
In this paper, we analyze a general predator-prey modelwith state feedback impulsive harvesting strategies in which the prey species displays a strongAllee effect.

Periodic or homoclinic orbit bifurcated from a heteroclinic loop for high-dimensional systems

open access: goldOpen Mathematics
Consider an autonomous ordinary differential equation in Rn{{\mathbb{R}}}^{n}, which has a heteroclinic loop. Assume that the heteroclinic loop consists of two degenerate heteroclinic orbits γ1{\gamma }_{1}, γ2{\gamma }_{2} and two saddle points with ...

Transitions of bifurcation diagrams of a forced heteroclinic cycle [PDF]

open access: greenJournal of Mathematical Analysis and Applications
A family of periodic perturbations of an attracting robust heteroclinic cycle defined on the two-sphere is studied by reducing the analysis to that of a one-parameter family of maps on a circle. The set of zeros of the family forms a bifurcation diagram on the cylinder. The different bifurcation diagrams and the transitions between them are obtained as

Experimental Observation of Magnetic Island Heteroclinic Bifurcation in Tokamaks

open access: yesPhysical Review Letters, 2021
We report empirical observations of magnetic island heteroclinic bifurcation for the first time. This behavior is observed in interacting coupled 2/1 tearing modes in the core of a DIII-D tokamak plasma. Poincaré maps constrained by measured magnetic amplitudes and phasing show bifurcation from heteroclinic to homoclinic topology in the 2/1 island as ...

Connected simple systems, transition matrices, and heteroclinic bifurcations [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1992
Given invariant sets A A , B B , and C C , and connecting orbits A → B A \to B and B → C B \to C , we state very general conditions under which they bifurcate to produce an A → C A \

Homoclinic and Heteroclinic Bifurcations in Vector Fields [PDF]

open access: green, 2010
An overview of homoclinic and heteroclinic bifurcation theory for autonomous vector fields is given. Specifically, homoclinic and heteroclinic bifurcations of codimension one and two in generic, equivariant, reversible, and conservative systems are reviewed, and results pertaining to the existence of multi-round homoclinic and periodic orbits and of ...

Analytic Solutions of 2D Cubic Quintic Complex Ginzburg-Landau Equation

open access: yesJournal of Applied Mathematics, 2023
The dynamical behaviour of traveling waves in a class of two-dimensional system whose amplitude obeys the two-dimensional complex cubic-quintic Ginzburg-Landau equation is deeply studied as a function of parameters near a subcritical bifurcation.
