Title: Applications of Points on Subvarieties of Tori
Abstract: A basic conjecture of Lang asserts that the intersection of a finitely generated subgroup of a torus with an algebraic subvariety has a simple description. We review the statement and some of the tools in its proof. It has many applications and we highlight some recent ones in Euclidean geometry, group theory, the spectral theory of metric graphs and quasicrystals.
