Expanding the simple pendulum's rotation solution in action-angle variables
Martin Lara, Sebastián Ferrer
Integration of Hamiltonian systems by reduction to action-angle variables has proven to be a successful approach. However, when the solution depends on elliptic functions the trans…

Poisson and symplectic reductions of 4-DOF isotropic oscillators. The van der Waals system as benchmark
Francisco Crespo, Gema María Díaz-Toca, Sebastián Ferrer +1
This paper is devoted to studying Hamiltonian oscillators in 1:1:1:1 resonance with symmetries, which include several models of perturbed Keplerian systems. Normal forms are comput…
