Weak type heterodimensional cycle bifurcation with orbit-flip

Science China Mathematics, 2011
In this paper, we study the weak type heterodimensional cycle with orbit-flip in its non-transversal orbit by using the local moving frame approach. For the first two subcases, we present the sufficient conditions for the existence, uniqueness and non-coexistence of the homoclinic orbit, heteroclinic orbit and periodic orbit.

Degenerate Orbit Flip Homoclinic Bifurcations with Higher Dimensions

Acta Mathematica Sinica, English Series, 2006
Bifurcations of a degenerate homoclinic orbit with orbit flip in high dimensional system are studied. By establishing a local coordinate system and a Poincare map near the homoclinic orbit, the existence and uniqueness of 1–homoclinic orbit and 1–periodic orbit are given. Also considered is the existence of 2–homoclinic orbit and 2–periodic orbit.

Bifurcations of double homoclinic flip orbits with resonant eigenvalues

Applied Mathematics and Mechanics, 2007
Concerns double homoclinic loops with orbit flips and two resonant eigenvalues in a four-dimensional system. We use the solution of a normal form system to construct a singular map in some neighborhood of the equilibrium, and the solution of a linear variational system to construct a regular map in some neighborhood of the double homoclinic loops, then

Pitchfork bifurcation and flip-flop operation with a coupled nonlinear system

Applied Optics, 1994
A ring cavity system consisting of two hybrid Michelson interferometers coupled together with feedback is constructed. This system shows spatial bifurcation and can be utilized as an all-optical flip-flop device. We demonstrate experimentally a flip-flop operation by use of only a positive pulse in this system.

Oscillation quenching and phase-flip bifurcation in coupled thermoacoustic systems

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019
Oscillatory instabilities, although ubiquitous in nature, are undesirable in many situations such as biological systems, swaying of bridges and skyscrapers, aero-acoustic flutter, prey-predator and disease spread models, and thermoacoustic systems, where they exhibit large amplitude periodic oscillations.

The cusp horseshoe and its bifurcations in the unfolding of an inclination-flip homoclinic orbit

Ergodic Theory and Dynamical Systems, 1994
AbstractDeng has demonstrated a mechanism through which a perturbation of a vector field having an inclination-flip homoclinic orbit would have a Smale horseshoe. In this article we prove that if the eigenvalues of the saddle to which the homoclinic orbit is asymptotic satisfy the condition 2λu > min{−λs, λuu} then there are arbitrarily small ...
