On the Conley decomposition of Mather sets


الملخص بالإنكليزية

In the context of Mathers theory of Lagrangian systems, we study the decomposition in chain-transitive classes of the Mather invariant sets. As an application, we prove, under appropriate hypotheses, the semi-continuity of the so-called Aubry set as a function of the Lagrangian.
