Variation of height in an isogeny class over a function field

Number Theory 2025-03-19 v1 Algebraic Geometry

Abstract

We give optimal estimates on the variation of the differential and modular heights within an isogeny class of abelian varieties defined over the function field of a curve (in any characteristic). We also prove a parallelogram inequality for abelian varieties in this context, and deduce corollaries of these results.
