Random Geometry

The laplacian on a periodic planar graph has a rich algebraic and integrable structure, which we usually don’t see when we do standard potential theory. We discuss the combinatorial, algebraic and integrable features of the laplacian, and in particular interpret combinatorially the points of the “spectral curve” of the laplacian in terms of probability measures on spanning trees and forests.
