Fundamental domains of cluster categories inside module categories

Abstract: Let $H$ be a finite dimensional hereditary algebra over an algebraically closed field, and let $\mathcal{C}<em>{H}$ be the corresponding cluster category. We give a description of the (standard) fundamental domain of $\mathcal{C}</em>{H}$ in the bounded derived category $\mathcal{D}<sup>{b}(H)$, and of the cluster-tilting objects, in terms of the category $\mod\Gamma$\ of finitely generated modules over a suitable tilted algebra $$ Furthermore, we apply this description to obtain (the quiver of) an arbitrary cluster-tilted algebra.
