A characterization of secant varieties of Severi varieties among cubic hypersurfaces

Baohua Fu, Yewon Jeong, Fyodor L. Zak

It is shown that an irreducible cubic hypersurface with nonzero Hessian and smooth singular locus is the secant variety of a Severi variety if and only if its Lie algebra of infini…
