Dans cet article, on étudie les mesures minimisantes de Hamiltoniens de Tonelli. Plus précisément, on explique quelles relations existent entre les fibrés de Green et différentes notions comme :•les exposants de Lyapunov des mesures minimisantes ;•les solutions KAM faibles. On en déduit par exemple que si tous les exposants de Lyapunov dʼune mesure minimisante μ sont nuls, alors le support de cette mesure est C 1 -régulier en μ-presque tout point.

In this article, we study the minimizing measures of the Tonelli Hamiltonians. More precisely, we study the relationships between the so-called Green bundles and various notions as:•the Lyapunov exponents of minimizing measures;•the weak KAM solutions. In particular, we deduce that the support of every minimizing measure μ, all of whose Lyapunov exponents are zero, is C 1 -regular μ-almost everywhere.
