Loop-erased Random Walk on Finite Graphs and the Rayleigh Process

چکیده
Let (Gn) ∞ n=1 be a sequence of finite graphs, and let Yt be the length of a loop-erased random walk on Gn after t steps. We show that for a large family of sequences of finite graphs, which includes the case in which Gn is the d-dimensional torus of size-length n for d ≥ 4, the process (Yt) ∞ t=0, suitably normalized, converges to the Rayleigh process introduced by Evans, Pitman, and Winter. Our proof relies heavily on ideas of Peres and Revelle, who used looperased random walks to show that the uniform spanning tree on large finite graphs converges to the Brownian continuum random tree of Aldous.

Convergence of the Length of the Loop-erased Random Walk on Finite Graphs to the Rayleigh Process
Let (Gn) ∞ n=1 be a sequence of finite graphs, and let Yt be the length of a loop-erased random walk on Gn after t steps. We show that for a large family of sequences of finite graphs, which includes the case in which Gn is the d-dimensional torus of size-length n for d ≥ 4, the process (Yt) ∞ t=0, suitably normalized, converges to the Rayleigh process introduced by Evans, Pitman, and Winter.

متن کاملScaling Limits of the Uniform Spanning Tree and Loop-erased Random Walk on Finite Graphs
Let x and y be chosen uniformly in a graph G. We find the limiting distribution of the length of a loop-erased random walk from x to y on a large class of graphs that include the torus Zn for d ≥ 5. Moreover, on this family of graphs we show that a suitably normalized finite-dimensional scaling limit of the uniform spanning tree is a Brownian continuum random tree.
متن کاملUniform spanning trees on Sierpiński graphs
We study spanning trees on Sierpiński graphs (i.e., finite approximations to the Sierpiński gasket) that are chosen uniformly at random. We construct a joint probability space for uniform spanning trees on every finite Sierpiński graph and show that this construction gives rise to a multi-type Galton-Watson tree. We derive a number of structural results, for instance on the degree distribution....
متن کاملThe loop - erased random walk and the uniform spanning tree on the four - dimensional discrete torus
Let x and y be points chosen uniformly at random from Z4n, the four-dimensional discrete torus with side length n. We show that the length of the loop-erased random walk from x to y is of order n(logn), resolving a conjecture of Benjamini and Kozma. We also show that the scaling limit of the uniform spanning tree on Z4n is the Brownian continuum random tree of Aldous. Our proofs use the techniq...
متن کاملLoop-Erased Random Walk and Poisson Kernel on Planar Graphs
Lawler, Schramm and Werner showed that the scaling limit of the loop-erased random walk on Z2 is SLE2. We consider scaling limits of the loop-erasure of random walks on other planar graphs (graphs embedded into C so that edges do not cross one another). We show that if the scaling limit of the random walk is planar Brownian motion, then the scaling limit of its loop-erasure is SLE2. Our main co...
