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 equivalent to stating that "V" is closed under taking subsemigroup and under taking quotient The second property implie that the empty product - that is, the trivial semigroup of one element - belongs to each variety. Hence a variety is necessarily non-empty. A variety of finite (ordered) monoid is a variety of finite (ordered) semigroup whose elements are monoid. That is, it is a set of (ordered) monoid satisfying the two conditions stated above. In order to give the topological definition of a variety of finite semigroup, some other definitions related to profinite word are needed. Let "A" be an
