Dans cet article, nous étudions les métriques à géodésiques homogènes, invariantes à gauche, sur des groupes de Lie simples connexes, où les métriques sont définies par les structures de variétés de drapeaux. Nous montrons que toutes ces métriques à géodésiques homogènes invariantes à gauche sur des groupes de Lie simples sont naturellement réductives.

In this paper, we investigate left-invariant geodesic orbit metrics on connected simple Lie groups, where the metrics are formed by the structures of flag manifolds. We prove that all these left-invariant geodesic orbit metrics on simple Lie groups are naturally reductive.
