关于四次域上有理椭圆曲线的挠率

On the torsion of rational elliptic curves over quartic fields

Enrique Gonzalez-Jimenez, Alvaro Lozano-Robledo

摘要:

设E是定义在Q上的椭圆曲线,G = E(Q)_tors是相应的挠子群.本文研究了对于给定的G,哪些可能的群G <= H可以出现使得H=E(K)_tors,对于[K:Q]=4,H是定义在四次数域上的椭圆曲线的挠结构中无限频繁出现的可能的挠结构之一.

英文摘要:

Let E be an elliptic curve defined over Q and let G = E(Q)_tors be the associated torsion subgroup. We study, for a given G, which possible groups G <= H could appear such that H=E(K)_tors, for [K:Q]=4 and H is one of the possible torsion structures that occur infinitely often as torsion structures of elliptic curves defined over quartic number fields.
