Partial tilting modules over m - replicated algebras ⋆
Let A be a hereditary algebra over an algebraically closed field k andA(m) be them-replicated algebra of A. Given an A(m)-module T , we denote by δ(T ) the number of non isomorphic indecomposable summands of T . In this paper, we prove that a partial tilting A(m)module T is a tilting A(m)-module if and only if δ(T ) = δ(A(m)), and that every partial tilting A(m)-module has complements. As an ap...
متن کاملTilting mutation for m-replicated algebras
Let A be a finite dimensional hereditary algebra over an algebraically closed field k, A(m) be the m-replicated algebra of A and Cm(A) be the m-cluster category of A. We investigate properties of complements to a faithful almost complete tilting A(m)-module and prove that the m-cluster mutation in Cm(A) can be realized in mod A (m), which generalizes corresponding results on duplicated algebras...
متن کاملOn Tilting Modules over Cluster-tilted Algebras
In this paper, we show that the tilting modules over a clustertilted algebra A lift to tilting objects in the associated cluster category CH . As a first application, we describe the induced exchange relation for tilting Amodules arising from the exchange relation for tilting object in CH . As a second application, we exhibit tilting A-modules having cluster-tilted endomorphism algebras. Cluste...
متن کاملFomin-Zelevinsky mutation and tilting modules over Calabi-Yau algebras
0. Introduction Let Λ be an algebra over a commutative noetherian ring R, which is finitely generated as an R-module. Sometimes we assume that R in addition satisfies one or more of the following conditions: local, complete, Gorenstein, normal. This paper deals mainly with algebras Λ which are Calabi-Yau of dimension d, called d-CY algebras for short. This means that the shift functor [d] gives...
متن کاملCharacter Formulas for Tilting Modules over Kac-moody Algebras
We show how to express the characters of tilting modules in a (possibly parabolic) category O over a Kac-Moody algebra in terms of the characters of simple highest weight modules. This settles, in lots of cases, Conjecture 7.2 of Kazhdan-Lusztig-Polynome and eine Kombinatorik für Kipp-Moduln, Representation Theory (An electronic Journal of the AMS) (1997), by the author, describing the characte...
