Bounded Height in Pencils of Finitely Generated Subgroups
Résumé
We prove height bounds concerning intersections of finitely generated subgroups in a torus with algebraic subvarieties, all varying in a pencil. This vastly extends the previously treated constant case and involves entirely different, and more delicate, techniques. The paper complements and sharpens Mordell-Lang by replacing finiteness by emptyness, for the intersection of varieties and subgroups, all moving in a pencil, except for bounded height values of the parameters (and excluding identical relations).
