Vertical coincidences of an elliptic curve defined over a number field
De Zoé Yvon
Let $E/F$ be an elliptic curve over a number field $F$. For a prime $p$, the extension $F(E[p^k])/F$ generated by the coordinates of the $p^k$-torsion points, is finite and Galois. We consider when the coincidence $F(E[p^k])=F(E[p^{k+1}])$ holds. Daniels and Lozano-Robledo classified such coincidences when $F=\mathbb{Q}$. In this talk, we will describe some results over a general number field $F$ and give additional possible coincidencesin this larger case.
