Planar $3$-webs and the boundary measurement matrix
Published 22 Dec 2023 in math.PR, math-ph, and math.MP | (2312.14761v1)
Abstract: We compute connection probabilities for reduced $3$-webs in the triple-dimer model on circular planar graphs using the boundary measurement matrix (reduced Kasteleyn matrix). As one application we compute several "$\text{SL}_3$ generalizations'' of the Lindstr{\o}m-Gessel-Viennot theorem, for "parallel" webs and for honeycomb webs. We also apply our results to the scaling limit of the dimer model in a planar domain, giving conformally invariant expressions for reduced web probabilities.
