摘要
本文证明了 中具有缺陷的节点超曲面至少有 个节点,且若其节点数不超过 且 ,则它包含一个平面或二次曲面。此外,我们证明了沿 次曲面分支且具有缺陷的 节点二重覆盖至少有 个节点。对于充分大的 ,我们构造了 中具有缺陷的 次节点超曲面的最大维数族。

v2: A proof for the Ciliberto-Di Gennaro conjecture is added (Section 5); Some minor corrections in the other sections. v3: some minor corrections in the abstract v4: The proof for the Ciliberto-Di Gennaro conjecture has been modified; The paper is split into two parts, the complete intersection case will be discussed in a different paper
