Abstract
We classify the possible torsion structures of rational elliptic curves over quintic number fields. In addition, 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 GâH could appear such that H=E(K)tors, for [K:Q]=5. In particular, we prove that at most there is one quintic number field K such that the torsion grows in the extension K/Q, i.e., E(Q)torsâE(K)tors.
