具有特殊双锥纤维的标记Godeaux曲面
Marked Godeaux surfaces with special bicanonical fibers
摘要:
本文研究了具有特殊双标准纤维的标记数值Godeaux曲面。基于标记Godeaux曲面的构造方法,我们给出了超椭圆双锥纤维和扭纤维存在性的完整刻画。此外,我们描述了如何家庭的里德和宫冈扭转$\mathbb{Z}/3\mathbb{Z}$和$\mathbb{Z}/5\mathbb{Z}$出现在我们的同源设置。
英文摘要:
In this paper we study marked numerical Godeaux surfaces with special bicanonical fibers. Based on our construction method of marked Godeaux surfaces we give a complete characterization for the existence of hyperelliptic bicanonical fibers and torsion fibers. Moreover, we describe how the families of Reid and Miyaoka with torsion $\mathbb{Z}/3\mathbb{Z}$ and $\mathbb{Z}/5\mathbb{Z}$ arise in our homological setting.
