The Multiplicity Problem for Periodic Orbits of Magnetic Flows on the 2-Sphere
We consider magnetic Tonelli Hamiltonian systems on the cotangent bundle of the 2-sphere, where the magnetic form is not necessarily exact. It is known that, on very low and on high energy levels, these systems may have only finitely many periodic orbits.

Homoclinics for strongly indefinite almost periodic second order Hamiltonian systems
Under certain assumptions, we prove the existence of homoclinic solutions for almost periodic second order Hamiltonian systems in the strongly indefinite case.
