WebSep 8, 2024 · This leads to the concept of representation type. An algebra has finite representation type if it has only finitely many finite-dimensional indecomposable modules up to isomorphism, otherwise it has infinite representation type. After discussing these notions, we determine the representation type for some classes of algebras. WebDec 20, 2012 · The following characterization for representation-finite Artin algebras is a direct consequence of Ringel’s partition theorem and the Successor Lemma. Lemma 1.2. Let Λ be an Artin algebra. Then the following are equivalent: (1) Λ is of finite representation type. (2) Λ admits only one GR segment. (3) Λ admits a finite GR …
WebDec 15, 2006 · Abstract. We investigate the cluster-tilted algebras of finite representation type over an algebraically closed field. We give an explicit description of the relations for the quivers for finite representation type. As a consequence we show that a (basic) cluster-tilted algebra of finite type is uniquely determined by its quiver. WebMay 21, 2024 · The results in Theorem 4.1(1) and (2) serve as an indication of why \(\tau \)-tilting finite algebras of infinite and of even wild representation type exist. Examples of \(\tau \) -tilting finite wild algebras are preprojective algebras of Dynkin type with at least six vertices [ 19 ] and wild contraction algebras [ 5 ].
