Abstract

Let EE be an elliptic curve over a number field KK with at least one real embedding and LL be a finite extension of KK. We generalize a result of Habegger to show that L(Etor)L(E_{\text{tor}}), the field generated by the torsion points of EE over LL, has the Bogomolov property. Moreover, the N\'eron-Tate height on E(L(Etor))E\big(L(E_{\text{tor}})\big) also satisfies a similar discreteness property. Our main tool is a general criterion of Plessis that reduces the problem to the existence of a supersingular prime for EE satisfying certain conditions.
