چکیده

Let X be a geometrically irreducible closed subvariety of an abelian variety A over a number field k such that X generates A. Let V be a finite-dimensional subspace of A(k) ⊗R, and let π : A(k) → V be the orthogonal projection relative to a Néron-Tate pairing 〈 , 〉 : A(k) × A(k) → R. For V = A(k) ⊗R, we prove that π(X(k)) = A(k) ⊗Q, and moreover, there exist c, c′ > 0 such that for any a ∈ A(k) ⊗ Q, {x ∈ X(k) : π(x) = a and h(x) < ch(a) + c′ } is Zariski dense in X.

Computing Néron-tate Heights of Points on Hyperelliptic Jacobians

It was shown by Faltings ([Fal84]) and Hriljac ([Hri85]) that the Néron-Tate height of a point on the Jacobian of a curve can be expressed as the self-intersection of a corresponding divisor on a regular model of the curve. We make this explicit and use it to give an algorithm for computing Néron-Tate heights on Jacobians of hyperelliptic curves. To demonstrate the practicality of our algorithm...

On a Theorem of Tate

A far-reaching generalization of this result is the Tate conjecture, asserting algebraicity of Tate classes, i.e., `-adic cohomology classes conformally invariant under the action of Frobenius. In this note we provide an alternative condition for the existence of surjective morphisms between abelian varieties and, more generally, Tate classes in the cohomology of products of arbitrary algebraic...

Computing Néron–severi Groups and Cycle Class Groups

Assuming the Tate conjecture and the computability of étale cohomology with finite coefficients, we give an algorithm that computes the Néron–Severi group of any smooth projective geometrically integral variety, and also the rank of the group of numerical equivalence classes of codimension p cycles for any p.

On the Néron-severi Groups of Fibered Varieties

We apply Tate’s conjecture on algebraic cycles to study the Néron-Severi groups of varieties fibered over a curve. This is inspired by the work of Rosen and Silverman, who carry out such an analysis to derive a formula for the rank of the group of sections of an elliptic surface. For a semistable fibered surface, under Tate’s conjecture we derive a formula for the rank of the group of sections ...
