WebHappel. THEOREM. Let A be a representation-finite algebra, let and A be its Auslander algebra. The following statements are equivalent: (a) A is simply connected; ... The results of Happel and Skowroriski imply respectively the equivalence of (a) and (d), and of (c) and (e). Since (c) clearly implies (b), we just have to show that (a) implies ... WebHappel theorem. As a continuation of [31], in this paper we further study the properties of the C-derived category, C-singularity category and so-called G(C)-defect category of A. In Section 2, we give some terminology and some preliminary results. In Section 3, we show that if C is closed under direct summands, then Kb(C) is a thick triangulated
