On the n-torsion subgroup of the Brauer group of a number field
Journal de théorie des nombres de Bordeaux, Volume 15 (2003) no. 1, pp. 199-204.

Given a number field K Galois over the rational field , and a positive integer n prime to the class number of K, there exists an abelian extension L/K (of exponent n) such that the n-torsion subgroup of the Brauer group of K is equal to the relative Brauer group of L/K.

Pour toute extension galoisienne K de et tout entier positif n premier au nombre de classes de K, il existe une extension abélienne L de K d’exposant n telle que le n-sous-groupe de torsion du groupe de Brauer de K est égal au groupe de Brauer relatif de L/K.
