The Multiplicity Problem for Periodic Orbits of Magnetic Flows on the 2-Sphere

open access: yesAdvanced Nonlinear Studies, 2017
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.
