Let Q be a finite union of Dynkin quivers, G subset of Aut(kQ) a finite abelian group, (Q) over cap the generalized McKay quiver of (Q, G) and Gamma(Q) the Auslander-Reiten quiver of kQ. Then G acts functorially on the quiver Gamma(Q). We show that the Auslander-Reiten quiver of k (Q) over cap coincides with the generalized McKay quiver of (Gamma(Q), G).
