论文摘要
结果表明,当且仅当其无限线性自动形态的谎言代数时,具有非零的黑森和平滑奇异基因座的不可约合的半表面是Severi品种的距离品种。
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 infinitesimal linear automorphisms admits a nonzero prolongation.
