The original publication of [AKM] contained several errors that the authors wish to correct in the following. Throughout, O will be a complete discrete valuation ring, and A will be a symmetric O-order (refer to [CR, Definition 23.1] for the definition of an O-order). We write latt-A for the category of A-lattices and the stable Auslander–Reiten quiver of A means that for latt-A. In [AKM], we introduced the stable Auslander–Reiten quiver of A and determined stable components of A that contain Heller lattices for the case A=O[X]/(Xn). The final result Theorem 3.1 is correct, but preparatory results Lemma 1.23 and Theorem 1.27 need to be stated more precisely. We correct those parts in this corrigendum. We also correct the careless statement of Lemma 1.21(3) in the original paper.
