PS : Simon Coste (ENS) : Local weak convergence and spectra of unimodular trees
This is an introduction to the study of limiting spectra of sparse graphs. I first introduce the notion of local weak convergence, explain the crucial "convergence theorem" for the empirical spectral measure, and I detail the representation of the limiting
