Abstract

Let HH be a finite dimensional hereditary algebra over an algebraically closed field, and let CH\mathcal{C}_{H} be the corresponding cluster category. We give a description of the (standard) fundamental domain of CH\mathcal{C}_{H} in the bounded derived category Db(H)\mathcal{D}^{b}(H), and of the cluster-tilting objects, in terms of the category modΓ\mod\Gamma \ of finitely generated modules over a suitable tilted algebra % \Gamma . Furthermore, we apply this description to obtain (the quiver of) an arbitrary cluster-tilted algebra.
