论文摘要
我们分析了特殊类别的Kummer八粒表面上的圆锥和线的配置。特别是,我们将圆锥数量的数量限制在$ 176 $中,并表明有一个独特的表面,圆锥形$ 176,这都是不可约的:它承认了其中一个Mukai集团的忠实行动。因此,我们还讨论了Mukai表面上的圆锥和线条:我们发现了一个双平面(在平滑的六曲线上被撞击),其中包含$ 8910 $光滑的锥体。
We analyze the configurations of conics and lines on a special class of Kummer octic surfaces. In particular, we bound the number of conics by $176$ and show that there is a unique surface with $176$ conics, all irreducible: it admits a faithful action of one of the Mukai groups. Therefore, we also discuss conics and lines on Mukai surfaces: we discover a double plane (ramified at a smooth sextic curve) that contains $8910$ smooth conics.
