The field $F$ generated by all torsion points of $E$ is an infinite, non-abelian Galois extension of the rationals which has unbounded, wild ramification above all primes. We prove that the absolute logarithmic Weil height of an element of $F$ is either zero or bounded from below by a positive constant depending only on $E$. We also show that the N\\'eron-Tate height has a similar gap on $E(F)$ and use this to determine the structure of the group $E(F)$.", "revisions": [ { "version": "v2", "updated": "2013-01-29T15:55:44.000Z" } ], "analyses": { "subjects": [ "11G50", "11G05", "14H52", "14G40" ], "keywords": [ "infinite non-abelian extensions", "small height", "absolute logarithmic weil height", "non-abelian galois extension", "torsion points" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1109.5859H" } } }
