%0 Journal Article %T Cluster categories, m-cluster categories and diagonals in polygons %A Karin Baur %J Mathematics %D 2009 %I arXiv %X The goals of this expository article are on one hand to describe how to construct ($m$-) cluster categories from triangulations (resp. from $m+2$-angulations) of polygons. On the other hand, we explain how to use translation quivers and their powers to obtain the $m$-cluster categories directly from the diagonals of a polygon. %U http://arxiv.org/abs/0912.3131v1
