The hyperelliptic Jacobian torsion conjecture

About 20 years old · traced to

Let KK be a number field, let gg be the genus of a hyperelliptic curve, and let pp be the prime occurring in the modular-tower construction. Let GKG_K be the absolute Galois group of KK, and let C≅Z/pk+1C\cong\mathbb Z/p^{k+1} be a cyclic subgroup of torsion on a hyperelliptic Jacobian of genus gg.

Hyperelliptic Jacobian torsion conjecture. For sufficiently large kk, there is no such CC for which GKG_K acts on CC through its cyclotomic action on ⟨e2πi/pk+1⟩\langle e^{2\pi i/p^{k+1}}\rangle.

The source states this as the hyperelliptic-Jacobian formulation equivalent to the weak conjecture for the indicated dihedral modular tower. No resolution is supplied in the excerpt.
