Cluster Variables and Perfect Matchings of Subgraphs of the Lattice
arXiv:1511.06055
Abstract
We give a combinatorial intepretation of cluster variables of a specific cluster algebra under a mutation sequence of period 6, in terms of perfect matchings of subgraphs of the brane tiling dual to the quiver associated with the cluster algebra.
