“…If X /Q is an elliptic curve without complex multiplication but with a nontrivial torsion over Q, one can repeat the construction of 7.4 and get an element of H 2 M (X, Q(2)), but not necessarily of H 2 (X, Q(2)) Z . Amusingly, the obstruction to integrality is related to the third Bernoulli polynomial in [11], [60]. In fact, it was only after the calculations of [11] that the cohomology of the integral model was incorporated into the conjectures.…”
