Additive combinatorics at infinity in the presence of a lattice

Abstract: (Joint with Spencer Dembner) If X is a closed algebraic subset of C^n, the Ax-Lindemann-Weierstrass theorem describes the Zariski-closure of the image of X under coordinate-wise exp in (C^*)^n as a union of algebraic subgroup cosets. Answering a question of Gallinaro, we give a [necessarily more complicated] description of the topological closure.
