Periodic solutions of Hamiltonian systems coupling twist with an isochronous center
We extend the Poincaré--Birkhoff Theorem to a Hamiltonian system which couples two systems with fairly different behaviors; the first one involves a twist assumption, while the second one is generated from a nonresonant isochronous center. By a suitable

The Uniform Isochronous Centers with Homogeneous Nonlinearities of Degree 6
Journal of Dynamical and Control SystemsIn this paper we study the topological phase portraits of polynomial differential systems with a uniform isochronous center, whose nonlinear parts are homogeneous polynomials of degree 6. We obtain all the distinct topological phase portraits in the Poincaré disc. For each phase portrait, we give a precise system to realize it.
