Abstract

For each prime number ss we introduce examples of (s1)(s-1)- and ss-representation infinite algebras in the sense of Herschend, Iyama and Oppermann, which arise from skew group algebras of some metacyclic groups embedded in SL(s,C)\mathrm{SL}(s,\mathbb{C}) and SL(s+1,C)\mathrm{SL}(s+1,\mathbb{C}). For this purpose, we give a description of the McKay quiver with a superpotential of such groups. Moreover we show that for s=2s=2 our examples correspond to the classical tame hereditary algebras of type D~\tilde{D}.
