A variant of the Mordell-Lang conjecture

Abstract

The Mordell-Lang conjecture (proven by Faltings, Vojta and McQuillan) states that the intersection of a subvariety VV of a semiabelian variety GG defined over an algebraically closed field k\mathbb{k} of characteristic 00 with a finite rank subgroup ΓG(k)\Gamma \le G(\mathbb{k}) is a finite union of cosets of subgroups of Γ\Gamma. We explore a variant of this conjecture when GG is a product of an abelian variety AA defined over k\mathbb{k} with the additive group Ga\mathbb{G}_a.
