3-Preprojective Algebras of Type D

Research output: Working paperPreprint


We present a family of selfinjective algebras of type D, which arise from the 3-preprojective algebras of type A by taking a ℤ3-quotient. We show that a subset of these are themselves 3-preprojective algebras, and that the associated 2-representation-finite algebras are fractional Calabi-Yau.
