On the torsion of rational elliptic curves over quartic fields

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 structure...

Description
Summary: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
