Abstract:
For an arbitrary field of characteristic different from 2 and 3, we construct versal families of elliptic curves whose 3-torsion is either rational or isomorphic to $\mathbb Z/3\mathbb Z\oplus \mu_3$ as a Galois module.
Bibliography: 10 titles.
Keywords:
elliptic curves, torsion points, Galois modules.
