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 is a variety of finite semigroup. However, the set of group is not a subvariety of the variety of (arbitrary) semigroups. Indeed, formula_17 is a monoid which is an infinite group. However, its submonoid formula_18 is not a group. Since the set of (arbitrary) groups contains a semigroup and does not contain one of its subsemigroup, it is not a variety. The main difference between the finite case and the infinite case, when groups are considered, is that a submonoid of a finite group is a finite group. While infinite groups are not closed under taking submonoid. The set of
