14th Northwest Probability Seminar – Recurrence of planar graph limits.


October 22, 2012


We prove that any distributional limit of finite planar graphs in which the degree of the root has an exponential tail is almost surely recurrent. As a corollary, we obtain that the uniform infinite planar triangulation and quadrangulation (UIPT and UIPQ) are almost surely recurrent, resolving a conjecture of Angel, Benjamini and Schramm.

Joint work with Ori Gurel-Gurevich.
