It is shown that if g1,…,gk are algebraic elements in SU(d) generating a dense subgroup, then the corresponding Hecke operator has a spectral gap.

On démontre que si g1,…,gk sont des éléments algébriques de SU(d) et le groupe engendré par g1,…,gk est dense, alors l'opérateur de Hecke défini par ces éléments a un trou spectral.
