  skos:definition """In mathematics, a Severi–Brauer variety over a field <i>K</i> is an algebraic variety <i>V</i> which becomes isomorphic to a projective space over an algebraic closure of <i>K</i>. The varieties are associated to central simple algebras in such a way that the algebra splits over <i>K</i> if and only if the variety has a rational point over <i>K</i>. Francesco Severi (1932) studied these varieties, and they are also named after Richard Brauer because of their close relation to the Brauer group.
