Artichoke production in Italy artichoke to Florence. By 1473, it had arrived in Venice. In 1915, 64,000 tons were produced. Italy produces dozens of varieties. 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
Degree of an algebraic variety Degree of an algebraic variety In mathematics, the degree of an affine or projective variety of dimension is the number of intersection points of the variety with hyperplanes in general position (for an algebraic set, the intersection points must be counted with their intersection multiplicity) The degree is not an intrinsic property of the variety, as it depends on a specific embedding of the variety in an affine or projective space. The degree of an hypersurface is equal to the total degree of its defining equation. A generalization of Bézout's theorem asserts that, if an intersection of projective hypersurfaces has
