Soit G un groupe de Lie connexe sur C, et soit Γ⊂G un sous-groupe discret cocompact. Nous démontrons que tout fibré vectoriel invariant sur G/Γ est semi-stable par rapport à toute structure hermitienne sur G/Γ provenant dʼune structure hermitienne sur G invariante par translations à droite.

Let G be a connected complex Lie group, and let Γ be a cocompact discrete subgroup of G. We prove that any invariant principal bundle on G/Γ is semistable with respect to any Hermitian structure on G/Γ given by some right-translation invariant Hermitian structure on G.
