A GEOMETRIC DESCRIPTION OF m-CLUSTER CATEGORIES
نویسنده
چکیده
We show that the m-cluster category of type An−1 is equivalent to a certain geometrically-defined category of diagonals of a regular nm+ 2-gon. This generalises a result of Caldero, Chapoton and Schiffler for m = 1. The approach uses the theory of translation quivers and their corresponding mesh categories. We also introduce the notion of the mth power of a translation quiver and show how it can be used to realise the m-cluster category in terms of the cluster category.

Geometric Construction of Cluster Algebras and Cluster Categories
In this note we explain how to obtain cluster algebras from triangulations of (punctured) discs following the approach of [FST06]. Furthermore, we give a description of m-cluster categories via diagonals (arcs) in (punctured) polygons and of m-cluster categories via powers of translation quivers as given in joint work with R. Marsh ([BM08a], [BM07]).
متن کاملA Geometric Description of the m-cluster Categories of Type Dn
This category was introduced in [1] and has been studied by Assem, Brüstle, Schiffler and Todorov [2], the authors [3], Thomas [4], Wralsen [5] and Zhu [6]. In particular, Thomas and Zhu have shown that it gives rise to the combinatorics of the generalized cluster complexes of Fomin and Reading [7] (defined by Tzanaki [8] for types A and B). It is known that C∆ is triangulated [1], Krull-Schmid...
متن کاملAN INTRODUCTION TO HIGHER CLUSTER CATEGORIES
In this survey, we give an overview over some aspects of the set of tilting objects in an $m-$cluster category, with focus on those properties which are valid for all $m geq 1$. We focus on the following three combinatorial aspects: modeling the set of tilting objects using arcs in certain polygons, the generalized assicahedra of Fomin and Reading, and colored quiver mutation.
متن کاملA geometric model for cluster categories of type Dn
We give a geometric realization of cluster categories of type Dn using a polygon with n vertices and one puncture is its center as a model. In this realization, the indecomposable objects of the cluster category correspond to certain homotopy classes of paths between two vertices. 0 Introduction Cluster categories were introduced in [BMRRT] and, independently, in [CCS1] for type An, as a means ...
متن کاملA GEOMETRIC DESCRIPTION OF THE m - CLUSTER CATEGORIES OF TYPE
We show that the m-cluster category of type Dn is equivalent to a certain geometrically-defined category of arcs in a punctured regular nm − m + 1-gon. This generalises a result of Schiffler for m = 1. We use the notion of the mth power of a translation quiver to realise the m-cluster category in terms of the cluster category. Introduction Let k be a field and Q a quiver of Dynkin type ∆. Let D...
