摘要
满足 的极小一般型代数曲面 称为 Horikawa 曲面。本文注记中研究了 Horikawa 曲面上的 -作用。主要结果表明,给定可容许对 使得 ,Gieseker 模空间 的所有连通分支均包含容许 -作用的曲面。另一方面,所考虑的例示可生成不容许 -Gorenstein 光滑化的正规稳定曲面。通过对每个满足 的可容许对 ,在 Gieseker 模空间 的 KSBA 紧化 中构造不可光滑化的正规曲面,说明了这一点。此外,所构造的曲面属于 中无典则模型的连通分支。

备注
Theorem 1 of the first version had to be modified because of mistakes in its proof. The second version of the paper was a provisional version where the mistakes were removed. The third version of the paper does not contain the mistakes and includes a stronger version both of Theorem 1 and Theorem 2. 12 pages
