Let C be a non-singular projective curve, and let A — > C be a (flat) family of abelian varieties, all defmed over a global field K. There are three natural height functions associated to such a family, namely a Weil height hc on C(AT), a canonical height hAti on the generic fiber An(K(C}\ and for each point teC(K) for which the special fiber At is non-singular, a canonical height hAt on At(K). Extending ideas of Dem'janenko and Manin ([2], [10]), we prove the following theorem comparing these… 
Unlikely intersections in families of abelian varieties and the polynomial Pell equation
Let S be a smooth irreducible curve defined over a number field k and consider an abelian scheme A over S and a curve C inside A , both defined over k . In previous works, we proved that, when A is a
Variation of the canonical height for a family of polynomials
A theorem of Tate asserts that, for an elliptic surface E/X defined over a number field k, and a section P of E, there exists a divisor D on X such that the canonical height of the specialization of
On the density of rational points on elliptic fibrations
1. Introduction Let X be an algebraic variety defined over a number field F. We will say that rational points are potentially dense if there exists a finite extension K/F such that the set of

In 1983, Silverman and Tate showed that the set of points in a 1-dimensional family of abelian varieties where a section of infinite order has “small height” is finite. We conjecture a generalization
Uniform Bound for the Number of Rational Points on a Pencil of Curves
Consider a one-parameter family of smooth, irreducible, projective curves of genus $g\ge 2$ defined over a number field. Each fiber contains at most finitely many rational points by the Mordell
Points Defined over Cyclic Quartic Extensions on an Elliptic Curve and Generalized Kummer Surfaces
Let E be an elliptic curve over a number field k. By the Mordell-Weil theorem the group E(K) of K-rational points on E, where K/k is a finite extension of k,is a finitely generated abelian group. We
Heights in families of abelian varieties and the Geometric Bogomolov Conjecture
On an abelian scheme over a smooth curve over $\overline{\mathbb Q}$ a symmetric relatively ample line bundle defines a fiberwise N\'eon-Tate height. If the base curve is inside a projective space,
Density of Integral Points on Algebraic Varieties
Let K be a number field, S a finite set of valuations of K, including the archimedean valuations, and OS the ring of S-integers. LetX be an algebraic variety defined over K and D a divisor on X. We
On the Average Value of the Canonical Height in Higher Dimensional Families of Elliptic curves
Given an elliptic curve E over a function field K=Q(T_1,...,T_n), we study the behavior of the canonical height ^h_(E_w) of the specialized elliptic curve E_w with respect to the height of w in Q^n.


Intersection numbers of sections of elliptic surfaces
The theory of elliptic surfaces over C draws on ideas and techniques from arithmetic, geometry and analysis. Let f : X ~ S be a minimal elliptic fibration with non-constant j-invariant, which

Arithmetic on algebraic varieties
Equations and Rings (Shafarevich I.R. (1988), (1987), Bourbaki N. (1962)). The machinery of algebraic geometry uses commutative rings instead of equations. Replacing a system of equations by a ring

It’s better to think of Algebraic Geometry as indicating a sub-area of mathematics as a whole, rather than a very precisely defined subfield.
It is shown that the p-component of the torsion of elliptic curves over a numerical field is bounded.
Estimate of the remainder term in Tate's formula
An estimate of the remainder term in Tate's formula is deduced and a property of finite order points of elliptic curves is pointed out.
