摘要:In long-range percolation on Z(d), we connect each pair of distinct points x and y by an edge independently at random with probability 1-exp(-beta parallel to x-y parallel to(-d-alpha)), where alpha> 0 is fixed and beta >= 0 is a parameter. In a previous paper, we proved that if 0 < alpha < d then the critical two-point function satisfies the spatially averaged upper bound 1/ r(d) & sum;(d)( x is an element of[-r,r]) (P)beta(c)(0 <-> x) <= r(-d+alpha) for every r >= 1. This upper bound is beli...

摘要:We investigate the bond percolation model on transient weighted graphs G induced by the excursion sets of the Gaussian free field on the corresponding metric graph. Under the sole assumption that its sign clusters do not percolate, we derive an extension of Lupu's formula for the two-point function at criticality. We then focus on the low-dimensional case 0 < nu < (alpha)/(2) , where alpha governs the polynomial volume growth of G and nu the decay rate of the Green's function on G. In particul...

摘要:In the graph shotgun assembly problem, we are given the balls of radius r around each vertex of a graph and asked to reconstruct the graph. We study the shotgun assembly of the Erd & odblac;s-R & eacute;nyi random graph G(n,p)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {G}}(n,p)$$\end{document} for a ...

摘要:We study inhomogeneous random graphs with a finite type space. For a natural generalization of the model as a dynamic network-valued process, the paper establishes the following results: (a) Functional central limit theorems for the infinite vector of microscopic type-densities and characterizations of the limits as infinite-dimensional conditionally Gaussian processes in a certain Banach space. (b) Functional (joint) central limit theorems for macroscopic observables of the giant component in...

摘要:We consider two different versions of the double dimer model on a planar domain, where we either fold a single dimer cover on a symmetric domain onto itself across the line of symmetry, or we superimpose two independent dimer covers on two, almost identical, domains that differ only on a certain portion of the boundary. This results in a collection of loops and doubled edges that, unlike in the classical double dimer case of Kenyon, are accompanied by arcs emanating from the line of symmetry o...

摘要:Consider the deterministic Skorokhod equation in the closed first quadrant: X-t=x(0)+f(t)+integral(t)(0)v(X-s)dL(s), where f:[0,infinity)-> R-2 is a continuous function, f(0)=0, X-t takes values in the quadrant for all t, and L-t is a process that starts at 0, is non-decreasing and continuous, and increases only at those times when is on the boundary of the quadrant. Suppose v on the positive x axis, equals (1,-a(2)) on the positive y axis, and v(0) points into the closed first quadrant. Let t...

摘要:We study the Isingp-spin glass model for largep. We show that for any inversetemperature root ln 2infinity, there exists exponentially many well-separated clusters such that(a) each cluster has exponentially small Gibbs mass, and (b) the clusters collectivelycontain all but a vanishing fraction of Gibbs mass. Moreover, these clusters consist ofconfigurations with energy near beta. Range of temperatures for which shattering occursis within thereplica symmetricregion. To the best of our knowledg...
