The periodic orbits problem in Tonelli Hamiltonian dynamics

Introductory Workshop: Hamiltonian systems, from topology to applications through analysis August 20, 2018 - August 24, 2018

Speaker(s): Marco Mazzucchelli (École Normale Supérieure de Lyon)
Location: MSRI: Simons Auditorium
  • Tonelli Hamiltonian

  • periodic orbits

  • closed geodesics

My talk will be an introductory lecture on the periodic orbits problem for Tonelli Hamiltonian systems. In a first part of the talk, I will recall the variational formulation of the problem, and its connections to Aubry-Mather theory and Weak KAM theory. I will then review some of the main known results on the multiplicity of periodic orbits with prescribed energy, and some of the celebrated open questions in the field, including the closed geodesics problem in Riemannian and Finsler manifolds.
