Counting Using Hall Algebras Ii. Extensions from Quivers
We count the Fq-rational points of GIT quotients of quiver representations with relations. We focus on two types of algebras – one is one-point extended from a quiver Q, and the other is the Dynkin A2 tensored with Q. For both, we obtain explicit formulas. We study when they are polynomial-count. We follow the similar line as in the first paper but algebraic manipulations in Hall algebra will b...
متن کاملSigned Quivers, Symmetric Quivers, and Root Systems.
We define a special sort of weighted oriented graphs, signed quivers. Each of these yields a symmetric quiver, i.e., a quiver endowed with an involutive anti-automorphism and the inherited signs. We develop a representation theory of symmetric quivers, in particular we describe the indecom-posable symmetric representations. Their dimensions constitute root systems corresponding to certain symme...
متن کاملCounting the Number of Elements in the Mutation Classes of An-Quivers
In this article we prove explicit formulae for the number of non-isomorphic cluster-tilted algebras of type Ãn in the derived equivalence classes. In particular, we obtain the number of elements in the mutation classes of quivers of type Ãn. As a by-product, this provides an alternative proof for the number of quivers mutation equivalent to a quiver of Dynkin type Dn which was first determined ...
متن کاملModuli spaces for Bondal quivers
Given a sufficiently nice collection of sheaves on an algebraic variety V , Bondal explained how to build a quiver Q along with an ideal of relations in the path algebra of Q such that the derived category of representations of Q subject to these relations is equivalent to the derived category of coherent sheaves on V . We consider the case in which these sheaves are all locally free and study ...
متن کاملCOUNTING THE NUMBER OF ELEMENTS IN THE MUTATION CLASSES OF QUIVERS OF TYPE Ãn
In this article we prove explicit formulae counting the elements in the mutation classes of quivers of type Ãn. In particular, we obtain the number of non-isomorphic clustertilted algebras of type Ãn. Furthermore, we give an alternative proof for the number of quivers of Dynkin type Dn which was first determined by Buan and Torkildsen in [4].
