What is.. Benjamini-Schramm convergence?

Vortrag von Yannick Krifka

Datum: 13.10.20  Zeit: 16.30 - 17.30  Raum: KOL H312

In a seminal paper Benjamini and Schramm introduced a notion of distributional limits for finite graphs. In this talk I will give an elementary introduction to Benjamini—Schramm convergence of finite graphs. We will then see how to generalize this to the more geometric context of Riemannian manifolds. If time permits I will explain how this can be used to obtain a new compactification of the moduli space of finite area hyperbolic surfaces.
