Hindry's integral torsion-point conjecture for abelian varieties
Hindry's integral torsion-point conjecture for abelian varieties
Let ) be a number field, let be a finite set of places of containing the archimedean places, and let be the ring of -integers. Let be an abelian variety, and let be a model of . Let be an effective divisor on , defined over , with at least one irreducible component that is not the translate of an abelian subvariety by a torsion point, and let be its Zariski closure in . Define to be the set of torsion points of whose closure in is disjoint from . Hindry's conjecture. The set is not Zariski dense in . This extends the Manin–Mumford phenomenon to torsion points satisfying an -integrality condition; the paper presents it as a general conjecture for abelian varieties, with the elliptic-curve case supplied by the main theorem. Its general status is not resolved in the supplied text.
