Abstract

We establish upper bounds for the smallest height of a generator of a number field k over the rational field \Q. Our first bound applies to all number fields k having at least one real embedding. We also give a second conditional result for all number fields k such that the Dedekind zeta-function associated to the Galois closure of k/\Q satisfies GRH. This provides a partial answer to a question of W. Ruppert.
