Do there exist expanders with non-negative curvature ?
I will briefly recall the framework of local weak limits of finite graphs introduced by I. Benjamini and O. Schramm, and then explain how this probabilistic viewpoint allowed me to answer a long-standing open question in discrete geometry (the one in the title), raised by E. Milman, A. Naor and Y. Ollivier.
