Abstract:  Let $Q$ be a finite union of Dynkin quivers, $G\subseteq{\rm Aut}(\Bbbk{Q})$ a finite abelian group, $\widehat{Q}$ the generalized McKay quiver of $(Q, G)$ and $\Gamma_Q$ the Auslander-Reiten quiver of $\Bbbk Q$. Then $G$ acts functorially on the quiver $\Gamma_Q$. We show that the Auslander-Reiten quiver of $\Bbbk\widehat{Q}$ coincides with the generalized McKay quiver of $(\Gamma_Q, G)$.
