Scorza variety Scorza variety In mathematics, a "k"-Scorza variety is a smooth projective variety, of maximal dimension among those whose "k"–1 secant varieties are not the whole of projective space. Scorza varieties were introduced and classified by , who named them after Gaetano Scorza. The special case of 2-Scorza varieties are sometimes called Severi varieties, after Francesco Severi. Zak showed that "k"-Scorza varieties are the projective varieties of the rank 1 matrices of rank "k" simple Jordan algebras. The Severi varieties are the non-singular varieties of dimension "n" (even) in P that can be isomorphically projected to a hyperplane and satisfy "N"=3"n"/2+2.
