AbstractLetG be a finitely generated subgroup of rankr of the multiplicative groupK* of a number field. We construct a basis α1,...,αr ofG such that for α∈G, writing
$$alpha = xi alpha _1^{x_{1.{ ext{ }}.{ ext{ }}.} } alpha _r^{x_r } $$
where ζ is a root of unity and where thexi are integers, we get a lower bound for the absolute heighth(α) in terms ofr and max
$$hleft( {alpha _i^{x_i } }
ight)$$
