关于McKay箭袋和Covering Spaces

On McKay Quiver and Covering Spaces

Jin Yun Guo

摘要:

本文研究了特殊线性群的有限子群$G$的McKay箭图与一般线性群的McKay箭图之间的关系。证明了$\mathrm{SL}(m,\mathbb C)$的有限子群$G$在$\mathrm{GL}(m,\mathbb C)$中的某个扩张的McKay复盖是$G$的McKay复盖的正则复盖,并且当以规范的方式将$G$嵌入到$\mathrm{GL}(m-1,\mathbb C)$中时,对于每个$i$,通过将$i$的Nakayama平移加回到$i$的箭头得到新的McKay复盖.我们还表明,某些有趣的例子麦凯箭获得这两种方式。

英文摘要:

In this paper, we study the relationship between the McKay quivers of a finite subgroups $G$ of special linear groups general linear groups, via some natural extension and embedding. We show that the McKay quiver of certain extension of a finite subgroup $G$ of $\mathrm{SL}(m,\mathbb C)$ in $\mathrm{GL}(m,\mathbb C)$ is a regular covering of the McKay quiver of $G$, and when embedding $G$ in a canonical way into $\mathrm{GL}(m-1,\mathbb C)$, the new McKay quiver is obtained by adding an arrow from the Nakayama translation of $i$ back to $i$ for each $i$. We also show that certain interesting examples of McKay quivers are obtained in these two ways.
