The purpose of this article is to determine all subfields Q(β) of fixed degree of a given algebraic number field Q(α). It is convenient to describe each subfield by a pair ( h , g ) of polynomials in Q[t] resp. Z[t] such that g is the minimal polynomial of β = h (α). The computations are done in unramified p -adic extensions and use information concerning subgroups of the Galois group of the normal closure of Q(α) obtained from the van der Waerden criterion. |
