Nous prouvons que la constante de Cowling–Haagerup dʼun produit libre réduit de groupes quantiques discrets faiblement moyennables de constante de Cowling–Haagerup égale à 1 est encore égale à 1.

We prove that the Cowling–Haagerup constant of a reduced free product of weakly amenable discrete quantum groups with Cowling–Haagerup constant equal to 1 is again equal to 1.
