Suppose that $G_j$ is a sequence of finite connected planar graphs, and in each $G_j$ a special vertex, called the root, is chosen randomly-uniformly. We introduce the notion of a distributional limit $G$ of such graphs. Assume that the vertex degrees of the vertices in $G_j$ are bounded, and the bound does not depend on $j$. Then after passing to a subsequence, the limit exists, and is a random rooted graph $G$. We prove that with probability one $G$ is recurrent. The proof involves the Circle… Expand

The Local Limit of the Uniform Spanning Tree on Dense Graphs
Let G be a connected graph in which almost all vertices have linear degrees and let $$\mathcal {T}$$T be a uniform spanning tree of G. For any fixed rooted tree F of height r we compute theExpand
Recurrence of planar graph limits
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 infiniteExpand

A notion of convergence for sequences of finite graphs { G n} that can be seen as a generalization of the Benjamini-Schramm convergence notion for bounded degree graphs and the left-convergence notion for dense graphs is presented. Expand
On the structure of random graphs with constant $r$-balls
We continue the study of the properties of graphs in which the ball of radius $r$ around each vertex induces a graph isomorphic to the ball of radius $r$ in some fixed vertex-transitive graph $F$,Expand
Hyperfinite graph limits

On the local geometry of graphs in terms of their spectra
It is proved that a sequence of graphs that share a common universal cover T and such that the proportion of eigenvalues of G n that lie within the support of the spectrum of T tends to 1 in the large n limit is asymptotically locally tree-like. Expand
Conformal growth rates and spectral geometry on distributional limits of graphs
For a unimodular random graph $(G,\rho)$, we consider deformations of its intrinsic path metric by a (random) weighting of its vertices. This leads to the notion of the {\em conformal growth exponentExpand

Using Glauber dynamics on processes to give a sufficient condition for a branching Markov chain to be factor of i.i.d. processes, this work proves a family of combinatorial statements about random $d-regular graphs. Expand


Harmonic functions on planar and almost planar graphs and manifolds, via circle packings
Abstract.The circle packing theorem is used to show that on any bounded valence transient planar graph there exists a non constant, harmonic, bounded, Dirichlet function. If $P$ is a bounded circleExpand

Abstract. Let G be a closed group of automorphisms of a graph X. We relate geometric properties of G and X, such as amenability and unimodularity, to properties of G-invariant percolation processesExpand
On the Cover Time of Planar Graphs
The cover time of a finite connected graph is the expected number of steps needed for a simple random walk on the graph to visit all the vertices. It is known that the cover time on any $n$-vertex,Expand

It is shown that the rate of growth of a graph with these properties is either linear or quadratic or exponential, and the same result holds more generally for locally finite, almost vertextransitive planar graphs. Expand
