Abstract

The Mordell--Lang conjecture for abelian varieties states that the intersection of an algebraic subvariety XX with a subgroup of finite rank is contained in a finite union of cosets contained in XX. In this article, we prove a uniform version of this conjecture, meaning that that the number of cosets necessary does not depend on the ambient abelian variety. To achieve this, we prove a general gap principle on algebraic points that extends the gap principle for curves embedded into their Jacobians, previously obtained by Dimitrov--Gao--Habegger and K\"{u}hne. Our new gap principle also implies the full uniform Bogomolov conjecture in abelian varieties.
