On the finiteness of Ш for motives associated to modular forms
Documenta mathematica, Tome 2 (1997), pp. 31-46
Let f be a modular form of even weight on Γ0(N) with associated motive Mf. Let K be a quadratic imaginary field satisfying certain standard conditions. We improve a result of Nekovar and prove that if a rational prime p is outside a finite set of primes depending only on the form f, and if the image of the Heegner cycle associated with K in the p-adic intermediate Jacobian of Mf is not divisible by p, then the p-part of the Tate-shafarevic group of Mf over K is trivial. An important ingredient of this work is an analysis of the behavior of “Kolyvagin test classes” at primes dividing the level N. In addition, certain complications, due to the possibility of f having a Galois conjugate self-twist, have to be dealt with.
