Periodic Solutions of Pendulum-Like Hamiltonian Systems in the Plane
By the use of a generalized version of the Poincaré-Birkhoff fixed point theorem, we prove the existence of at least two periodic solutions for a class of Hamiltonian systems in the plane, having in mind the forced pendulum equation as a particular case. Our approach is closely related to the one used by Franks in , but the proof remains at a more elementary level.
