Action functional as an early warning indicator in the space of probability measures via Schrödinger bridge. [PDF]

open access: yesQuant Biol
Abstract Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states with Onsager–Machlup action functional, to investigate the evolutionary transition dynamics ...

Are physiological oscillations physiological? [PDF]

open access: yesJ Physiol
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Bifurcation of big periodic orbits through symmetric homoclinics‎, ‎application to Duffing equation [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
‎We consider a planar symmetric vector field that undergoes a homoclinic bifurcation‎. ‎In order to study the existence of exterior periodic solutions of the vector field around broken symmetric homoclinic orbits‎, ‎we investigate the existence of fixed ...

A nonzero solution for bounded selfadjoint operator equations and homoclinic orbits of Hamiltonian systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We obtain an existence theorem of nonzero solution for a class of bounded selfadjoint operator equations. The main result contains as a special case the existence result of a nontrivial homoclinic orbit of a class of Hamiltonian systems by Coti Zelati ...

On the Homoclinic Orbits of the Lü System [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2017
In this paper, the existence of homoclinic orbits of the equilibrium point [Formula: see text] is demonstrated in the case of the Lü system for parameter values not reported by G. A. Leonov. In addition, some simulations are shown that agree with our theoretical analysis.

Scarring by Homoclinic and Heteroclinic Orbits [PDF]

open access: yesPhysical Review Letters, 2006
In addition to the well known scarring effect of periodic orbits, we show here that homoclinic and heteroclinic orbits, which are cornerstones in the theory of classical chaos, also scar eigenfunctions of classically chaotic systems when associated closed circuits in phase space are properly quantized, thus introducing strong quantum correlations.

Global orbit of a complicated nonlinear system with the global dynamic frequency method

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
Global orbits connect the saddle points in an infinite period through the homoclinic and heteroclinic types of manifolds. Different from the periodic movement analysis, it requires special strategies to obtain expression of the orbit and detect the ...

Existence of homoclinic orbit in generalized Liénard type system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
The object of this paper is to study the existence and nonexistence of an important orbit in a generalized Liénard type system. This trajectory is doubly asymptotic to an equilibrium solution, i.e., an orbit which lies in the intersection of the stable ...

Continuation of Homoclinic Orbits in Matlab [PDF]

open access: yes, 2005
We have added the functionality for continuing homoclinic orbits to cl_matcont, a user-friendly matlab package for the study of dynamical systems and their bifurcations. It is now possible to continue homoclinic-to-hyperbolic-saddle and homoclinic-to-saddle-node orbits.

Codimension 3 bifurcation from orbit-flip homoclinic orbit of weak type

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
This article is devoted to the research of a new codimension 3 homoclinic orbit bifurcation, which is the orbit-flip of weak type. Such kind of homoclinic orbit is a degenerate case of the orbit-flip homoclinic orbit.
