Abstract

Let A be a hereditary algebra over an algebraically closed field. We prove that an exact fundamental domain for the m-cluster category of A is the m-left part of the m-replicated algebra A(m)A^{(m)} of A. Moreover, we obtain a one-to-one correspondence between the tilting objects in the m-cluster category (that is, the m-clusters) and those tilting A(m)A^{(m)}-modules for which all non projective-injective direct summands lie in the m-left part of A(m)A^{(m)}.
