Bifurcation of Nongeneric Homoclinic Orbit Accompanied by Pitchfork Bifurcation

open access: yesAbstract and Applied Analysis, 2014
The bifurcation of a nongeneric homoclinic orbit (i.e., the orbit comes from the equilibrium along the unstable manifold instead of the center manifold) connecting a nonhyperbolic equilibrium is investigated, and the nonhyperbolic equilibrium undergoes ...

Robust homoclinic orbits in planar systems with Preisach hysteresis operator [PDF]

open access: yes, 2016
We construct examples of robust homoclinic orbits for systems of ordinary differential equations coupled with the Preisach hysteresis operator. Existence of such orbits is demonstrated for the first time.

Resonant Homoclinic Flips Bifurcation in Principal Eigendirections

open access: yesAbstract and Applied Analysis, 2013
A codimension-4 homoclinic bifurcation with one orbit flip and one inclination flip at principal eigenvalue direction resonance is considered. By introducing a local active coordinate system in some small neighborhood of homoclinic orbit, we get the ...

Continuum-wise expansive homoclinic classes for robust dynamical systems

open access: yesAdvances in Difference Equations, 2019
In the study, we consider continuum-wise expansiveness for the homoclinic class of a kind of C1 $C^{1}$-robustly expansive dynamical system. First, we show that if the homoclinic class H(p,f) $H(p, f)$, which contains a hyperbolic periodic point p, is R ...

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 ...

Homoclinic bifurcations in a planar dynamical system

open access: yes, 2022
S.1183-1191The homoclinic bifurcation properties of a planar dynamical system are analyzed and the corresponding bifurcation diagram is presented. The occurrence of two Bogdanov-Takens bifurcation points provides two local existing curves of homoclinic ...

Dynamics of a state-dependent delay-differential equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
We present a detailed study of a scalar differential equation with threshold state-dependent delayed feedback. This equation arises as a simplification of a gene regulatory model.

Homoclinic and heteroclinic solutions to a hepatitis C evolution model

open access: yesOpen Mathematics, 2018
Homoclinic and heteroclinic solutions to a standard hepatitis C virus (HCV) evolution model described by T. C. Reluga, H. Dahari and A. S. Perelson, (SIAM J. Appl. Math., 69 (2009), pp. 999–1023) are considered in this paper.

Synchronization of "Hopf/homoclinic" bursting with "SubHopf/homoclinic" bursting

open access: yesActa Physica Sinica, 2013
Taking the modified Morris-Lecar neuron model for example, we consider the synchronous behaviour between "Hopf/homoclinic" bursting and "SubHopf/homoclinic" bursting. Firstly, the synchronization between two coupled bursting neurons with the same topological type is investigated numerically, and the results show that the coupling strength reaching the ...

Rigorous numerics for symmetric homoclinic orbits in reversible dynamical systems [PDF]

open access: yes, 2007
summary:We propose a new rigorous numerical technique to prove the existence of symmetric homoclinic orbits in reversible dynamical systems. The essential idea is to calculate Melnikov functions by the exponential dichotomy and the rigorous numerics. The
