Spectral gaps in SU(d)
Comptes Rendus. Mathématique, Volume 348 (2010) no. 11-12, pp. 609-611.

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.
