                       Recurrence of planar graph limits
 
Abstract:
We will show that any distributional limit of finite planar graphs in which the
degree of the root decays exponentially is almost surely recurrent. As a
corollary, we obtain that the uniform infinite planar
triangulation/quadrangulation (UIPT/UIPQ) are almost surely recurrent,
resolving conjectures of Angel, Benjamini and Schramm. Joint work with Asaf
Nachmias.
