Planar Hamiltonian systems: index theory and applications to the existence of subharmonics

Alberto Boscaggin, Eduardo Muñoz-Hernández

We consider a planar Hamiltonian system of the type $J z^{'} = \nabla_{z} H (t, z)$ , where $H : R \times R^{2} \to R$ is a function periodic in the time variable, s…

Periodic solutions to relativistic Kepler problems: a variational approach

Alberto Boscaggin, Walter Dambrosio, Duccio Papini

We study relativistic Kepler problems in the plane. At first, using non-smooth critical point theory, we show that under a general time-periodic external force of gradient type the…
