On the Homoclinic Orbits of the Lü System [PDF]
International 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]
Physical 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.

Continuation of Homoclinic Orbits in Matlab [PDF]
, 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.

Abstract and Applied Analysis, 2013 We study a class of nonperiodic damped vibration systems with asymptotically quadratic terms at infinity. We obtain infinitely many nontrivial homoclinic orbits by a variant fountain theorem developed recently by Zou.

Homoclinic Orbits in Slowly Varying Oscillators
SIAM Journal on Mathematical Analysis, 1987 Perturbed Hamiltonian systems of the type \(\dot x=f(x)+\epsilon g(x,t,\lambda)\) are considered, where \(f: {\mathbb{R}}^ 3\to {\mathbb{R}}^ 2\), \(g: {\mathbb{R}}^{4+k}\to {\mathbb{R}}^ 3\) are sufficiently smooth, g(x,t,\(\lambda)\) is periodic in t, \(\lambda\) is a k-vector parameter, and \(\epsilon\) is a small positive parameter.

Известия высших учебных заведений: Прикладная нелинейная динамикаTopic of the paper. Bounded stationary (i.e. independent in time) spatially one-dimensional solutions of a quasilinear parabolic PDE are studied on the whole real line.

On homoclinic and heteroclinic orbits for Hamiltonian systems
Differential and Integral Equations, 1997 The authors give sufficient conditions for the existence of homoclinic and heteroclinic orbits of Hamiltonian systems \[ u''-L(t)u+V_u(t,u)=0,\tag{*} \] where \(L\) is a symmetric positive definite \(n\times n\) matrix and the potential \(V\) is supposed to be superquadratic in \(u\).

Homoclinic Orbits for a Class of Nonperiodic Hamiltonian Systems
Abstract and Applied Analysis, 2012 We study the following nonperiodic Hamiltonian system ż=JHz(t,z), where H∈C1(R×R2N,R) is the form H(t,z)=(1/2)B(t)z⋅z+R(t,z). We introduce a new assumption on B(t) and prove that the corresponding Hamiltonian operator has only point spectrum.
