Descriptif
In this talk I will briefly recall the framework of local weak limits of finite graphs introduced by I. Benjamini and O. Schramm, and explain how this probabilistic viewpoint allowed me to answer a classical open question in discrete geometry raised by E. Milman, A. Naor and Y. Ollivier.
