Exact solution of the Seven-Vertex Model on a dynamical lattice
Mateus da Silva Junca, Ivan Kostov, Andre Alves Lima
We give the complete solution of the one-parameter deformation of the six-vertex model on dynamical lattice introduced in [1] and dubbed gravitational seven-vertex model. The stati…

A Matrix Model for Higher-Genus Fuss--Catalan Numbers
Anatol Kirillov, Ivan Kostov
The genus-g Fuss--Catalan (FC) number counts the number of ways to obtain a genus-g surface by identifying the edges of a pn-gon via p-valent hyperedges. For p=2 these are the genu…
