Homoclinic orbits at infinity for second-order Hamiltonian systems with fixed energy

open access: yesElectronic Journal of Differential Equations, 2015
We obtain the existence of homoclinic orbits at infinity for a class of second-order Hamiltonian systems with fixed energy. We use the limit for a sequence of approximate solutions which are obtained by variational methods.

Infinitely many homoclinic orbits for Hamiltonian systems with group symmetries

open access: yesElectronic Journal of Differential Equations, 1999
This paper deals via variational methods with the existence of infinitely many homoclinic orbits for a class of the first-order time-dependent Hamiltonian systems $$ dot{z}=JH_z(t,z) $$ without any periodicity assumption on $H$, providing that $H(t,z ...

The Homoclinic Orbits in the Liénard Plane

open access: yesJournal of Mathematical Analysis and Applications, 1995
In reply to a question, posed by Roberto Conti, concerning the stability properties of the origin to a pseudolinear system in \(\mathbb{R}^ 2\), the situation is clarified for the well-known Liénard system. The notion of the maximal elliptic sector is shown to play an important role with respect to a zero solution to be a positive global (weak ...

Multitudinous potential homoclinic and heteroclinic orbits seized

open access: yesElectronic Research Archive
Revisiting a newly reported modified Chen system by both the definitions of $ \alpha $-limit and $ \omega $-limit set, Lyapunov function and Hamiltonian function, this paper seized a multitude of pairs of potential heteroclinic orbits to (1) $ E_{0 ...
