We present several results on the connectivity of McKay quivers of finite-dimensional complex representations of finite groups, with no restriction on the faithfulness or self-duality of the representations. We give examples of McKay quivers, as well as quivers that cannot arise as McKay quivers, and discuss a necessary and sufficient condition for two finite groups to share a connected McKay quiver.

MCKAY QUIVERS 的连接特性

我们提出了几个关于有限群的有限维复数表示的 McKay 颤动的连通性的结果，对表示的忠实性或自对偶性没有限制。我们给出了 McKay 颤动的例子，以及不能作为 McKay 颤动出现的颤动，并讨论了两个有限群共享一个连通的 McKay 颤动的充要条件。
