Bogomolov Property of some infinite nonabelian extensions of a totally $v$-adic field

Abstract

Let $E$ be an elliptic curve defined over a number field $K$ and let $v$ be a finite place of $K$. Write $K^{tv}$ the maximal extension of $K$ in which $v$ is totally split and $L$ the field generated over $K^{tv}$ by all torsion points of $E$. Under some conditions, we will show that the absolute logarithmic Weil height (resp. Néron-Tate height) of any element of $L^{\ast }$ (resp. $E(L)$) is either $0$ or bounded from below by a positive constant depending only on $E,K$ and $v$. This lower bound will be explicit in the toric case when $K=\mathbb{Q}$.

arXiv commentTheorem 1.6 has been improved. As a very special case, we provide, for every D\in\N and every elliptic curve E defined over Q(\sqrt{D}), an explicit lower bound of the Weil height for points lying in Q(\sqrt{D}, E_\tors)^*\backslash μ_\infty
