Artichoke Artichoke The globe artichoke ("Cynara cardunculus" var. "scolymus") is a variety of a species of thistle cultivated as a food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form. Another variety of the same species is the cardoon, a perennial plant native to the Mediterranean region. Both wild forms and cultivated varieties (cultivars) exist. This vegetable grows
Abelian variety of "n"-torsion points forms a finite flat group scheme. The union of the "p"-torsion points, for all "n", forms a p-divisible group. Deformations of abelian schemes are, according to the Serre–Tate theorem, governed by the deformation properties of the associated "p"-divisible groups. A semiabelian variety is a commutative group variety which is an extension of an abelian variety by a torus. Abelian variety In mathematics, particularly in algebraic geometry, complex analysis and algebraic number theory, an abelian variety is a projective algebraic variety that is also an algebraic group, i.e., has a group law that can be defined by regular
