Multiple homoclinic solutions for superquadratic Hamiltonian systems

open access: yesElectronic Journal of Differential Equations, 2016
In this article we study the existence of infinitely many homoclinic solutions for a class of second-order Hamiltonian systems $$ \ddot{u}-L(t)u+W_u(t,u)=0, \quad \forall t\in\mathbb{R}, $$ where L is not required to be either uniformly positive ...

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.
