On the behavior of periodic solutions of planar autonomous Hamiltonian systems with multivalued periodic perturbations

Oleg Makarenkov, Luisa Malaguti, Paolo Nistri

Aim of the paper is to provide a method to analyze the behavior of $T$-periodic solutions $x_\eps, \eps>0$, of a perturbed planar Hamiltonian system near a cycle $x_0$, of smallest…
