Specialization of canonical heights on abelian varieties
Alexander Carney
Given a family of abelian varieties over a quasiprojective smooth curve over a global field and a point on the generic fiber, we show that the Néron-Tate canonical height…

Heights and arithmetic dynamics over finitely generated fields
Alexander Carney
We develop a theory of vector-valued heights and intersections defined relative to finitely generated extensions K/k. These generalize both number field and geometric heights. When…

The arithmetic Hodge Index Theorem and rigidity of dynamical systems over function fields
Alexander Carney
In one of the fundamental results of Arakelov's arithmetic intersection theory, Faltings and Hriljac (independently) proved the Hodge Index Theorem for arithmetic surfaces by relat…
