Abstract

In this paper, we study the relationship between the McKay quivers of a finite subgroups GG 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 GG of SL(m,C)\mathrm{SL}(m,\mathbb C) in GL(m,C)\mathrm{GL}(m,\mathbb C) is a regular covering of the McKay quiver of GG, and when embedding GG in a canonical way into GL(m1,C)\mathrm{GL}(m-1,\mathbb C), the new McKay quiver is obtained by adding an arrow from the Nakayama translation of ii back to ii for each ii. We also show that certain interesting examples of McKay quivers are obtained in these two ways.
