Durif producers of Durif. The grape can also be found in Israel, Brazil, Argentina, Chile, and Mexico. Confirmed as recently as 1997, old plantings of Durif continued to be used to produce popular wine in the Rutherglen, Victoria region of Australia. Durif is now grown in other wine regions of Australia, such as Riverina and Riverland, with over under cultivation by 2000. DNA fingerprinting has shown that the majority of Petite Sirah plantings in California are actually Durif. Some vineyards were found to be a field blend of Durif and other varieties, such as Mondeuse noire, all labeled as "Petite Sirah".
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
