Explicit lower bounds for the height in Galois extensions of number fields

Number Theory 2024-11-19 v4

Abstract

Amoroso and Masser proved that for every real ϵ>0\epsilon > 0, there exists a constant c(ϵ)>0c(\epsilon)>0, such that for every algebraic number α\alpha with Q(α)/Q\mathbb{Q}(\alpha)/\mathbb{Q} being a Galois extension, the height of α\alpha is either 0 or at least c(ϵ)[Q(α):Q]ϵc(\epsilon) [\mathbb{Q}(\alpha):\mathbb{Q}]^{-\epsilon}. In this article we establish an explicit version of this theorem.
