Arithmetic of abelian varieties Arithmetic of abelian varieties In mathematics, the arithmetic of abelian varieties is the study of the number theory of an abelian variety, or family of those. It goes back to the studies of Pierre de Fermat on what are now recognized as elliptic curves; and has become a very substantial area both in terms of results and conjectures. Most of these can be posed for an abelian variety "A" over a number field "K"; or more generally (for global fields or more general finitely-generated rings or fields). There is some tension here between concepts: "integer point" belongs in a sense
