Durif of the officially sanctioned grapes of the Côtes du Rhône AOC, Petite Sirah's linking to Durif caused the California's Rhone Rangers to add the grape to its listings of wine in 2002. In Israel, Petite Sirah had a history much like that in California—historically used as a blending grape to add body to inferior wines. However, Petite Sirah has recently experienced somewhat of a revival, both in high-end blends and bottled as a single or majority variety. The UC Davis-trained winemaker and Ph.D. chemist Ya'ir Margalit, familiar with the grape from his time in California, showed that Petite Sirah need
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
