Artichoke production in Italy Artichoke production in Italy Artichoke production in Italy has a long history. Italy is the world's largest producer of artichokes. With Spain and France, the three countries produce more than 80% of the world's artichokes. There are two theories as to its origin: artichokes may have come from the Levant, derived from the cardoon or thistle through a cross-fertilization process, while others attribute it to the work of Italian horticulturists. The first record of artichoke cultivation in Italy was during the fifteenth century in Naples, where it was considered a new food species. In 1466, Filippo Strozzi brought the first
Variety of finite semigroups an arbitrary set "P" of profinite identity "u" = "v", the set of semigroup satisfying "P" is the intersection of the set of semigroups satisfying all of those profinite identities. That is, it is an intersection of varieties of finite semigroup, and this a variety of finite semigroup. The definition of variety of finite semigroup is inspired by the notion of variety of universal algebra. We recall the definition of a variety in universal algebra. Such a variety is, equivalently: The main difference between the two notions of variety are now given. In this section "variety of (arbitrary) semigroup" means
