arXiv:1309.1019
Abstract
This paper surveys some results by the author and collaborators on the existence of invariant Lagrangian graphs for Tonelli Hamiltonian systems. The presentation is based on an invited talk by the author at XIX Congresso Unione Matematica Italiana (Bologna, 12-17 Sept. 2011).
