Le but de cet article est d’expliquer comment calculer exactement le nombre de classes d’isomorphismes d’extensions abéliennes de en degré inférieur ou égal à et de discriminant majoré par une borne donnée. On parvient par exemple à calculer le nombre de corps cubiques cycliques de discriminant inférieur ou égal à .
This paper explains how to compute exactly the number of isomorphism classes of abelian extensions of in degree less than or equal to having their discriminant bounded by a given integer. For example, we are able to compute the number of cyclic cubic fields of discriminant less than or equal to .
