Permutons, which are probability measures on the unit square with uniform marginals, are the natural scaling limits for sequences of (random) permutations. We introduce a -dimensional generalization of these measures for all , which we call –dimensional permutons, and extend — from the two-dimensional setting — the theory to prove convergence of sequences of (random) …

We give a sum over weighted planar surfaces formula for Wilson loop expectations in the large- limit of strongly coupled lattice Yang–Mills theory, in any dimension. The weights of each surface are simple and expressed in terms of products of signed Catalan numbers. In establishing our results, the main novelty is to convert a recursive …

Permutons constructed from a Liouville quantum gravity surface and a pair of space-filling Schramm-Loewner evolutions (SLEs) have been shown — or are conjectured — to describe the scaling limit of various natural models of random constrained permutations.  We prove that, in two distinct and natural settings, these permutons uniquely determine, modulo rotation, scaling, translation and …
