Bounded Height Conjecture for unlikely intersections in abelian varieties
Bounded Height Conjecture for unlikely intersections in abelian varieties
Let be an abelian variety of dimension , let be an irreducible subvariety of dimension , and let be a subgroup of finite rank. The variety is weak-transverse if it is not contained in any proper algebraic subgroup of , and transverse if it is not contained in any translate of a proper algebraic subgroup. For a height-induced seminorm, let and . Define , with ranging over abelian subvarieties of codimension at least . Bounded Height Conjecture. There exists and a nonempty Zariski-open set such that:
- If is weak-transverse, then has bounded height.
- If is transverse, then has bounded height.
The conjecture is the height component of the preceding non-density statement. The source notes that the weak-transverse assertion implies the transverse one, whereas the converse does not hold in general.
