Unimodular random trees
We consider unimodular random rooted trees (URTs) and invariant forests in Cayley graphs. We show that URTs of bounded degree are the same as the law of the component of the root in an invariant percolation on a regular tree. We use this to give a new proof that URTs are sofic, a result of Elek. We show that ends of invariant forests in the hyperbolic plane converge to ideal boundary points. We...

متن کاملEnds of Manifolds: Recent Progress
In this note we describe some recent work on ends of manifolds. In particular, we discuss progress on two different approaches to generalizing Siebenmann’s thesis to include manifolds with non-stable fundamental groups at infinity.
متن کاملProcesses on Unimodular Random Networks
We investigate unimodular random networks. Our motivations include their characterization via reversibility of an associated random walk and their similarities to unimodular quasi-transitive graphs. We extend various theorems concerning random walks, percolation, spanning forests, and amenability from the known context of unimodular quasi-transitive graphs to the more general context of unimodu...
متن کاملDynamics on Unimodular Random Graphs
This paper is centered on covariant dynamics on random graphs and random networks (marked graphs), which can be described as rules to navigate the vertices that are preserved by graph/network isomorphisms. Such dynamics are referred to as vertex-shifts here. Unimodular random networks can be heuristically described as networks seen from a vertex chosen uniformly at random, both in the finite an...
