Double Dimer Covers on Snake Graphs from Super Cluster Expansions

Combinatorics 2021-11-18 v2

Abstract

In a recent paper, the authors gave combinatorial formulas for the Laurent expansions of super λ\lambda-lengths in a marked disk, generalizing Schiffler's TT-path formula. In the present paper, we give an alternate combinatorial expression for these super λ\lambda-lengths in terms of double dimer covers on snake graphs. This generalizes the dimer formulas of Musiker, Schiffler, and Williams.
