C-vectors and dimension vectors for cluster-finite quivers
arXiv:1212.1846
Abstract
Let be a quiver with a non degenerate potential. We give a new description of the \textbf{c}-vectors of . We use it to show that, if is mutation equivalent to a Dynkin quiver, then the set of positive -vectors of the cluster algebra associated to coincides with the set of dimension vectors of the indecomposable modules over the Jacobian algebra of .
