Abstract
Let be an elliptic curve defined over , and let be the torsion group for some cubic field which does not occur over . In this paper, we determine over which types of cubic number fields (cyclic cubic, non-Galois totally real cubic, complex cubic or pure cubic) can occur, and if so, whether it can occur infinitely often or not. Moreover, if it occurs, we provide elliptic curves together with cubic fields so that .
