Abstract
Let be a finite dimensional hereditary algebra over an algebraically closed field, and let be the corresponding cluster category. We give a description of the (standard) fundamental domain of in the bounded derived category , and of the cluster-tilting objects, in terms of the category \ of finitely generated modules over a suitable tilted algebra Furthermore, we apply this description to obtain (the quiver of) an arbitrary cluster-tilted algebra.
