摘要：In this paper, we provide relations among the following properties: (a) the tail triviality of a probability measure mu on the configuration space Gamma; (b) the finiteness of a suitable L-2-transportation-type distance (d) over bar (Gamma); (c) the irreducibility of local mu-symmetric Dirichlet forms on Gamma. As an application, we obtain the ergodicity (i.e., the convergence to the equilibrium) of interacting infinite diffusions having logarithmic interaction and arising from determinantal/p...

摘要：We study two-dimensional critical bootstrap percolation models. We establish that a class of these models including all isotropic threshold rules with a convex symmetric neighbourhood, undergoes a sharp metastability transition. This extends previous instances proved for several specific rules. The paper supersedes a draft by Alexander Holroyd and the first author from 2012. While it served a role in the subsequent development of bootstrap percolation universality, we have chosen to adopt a mo...

摘要：We consider the problem of finding the initial vertex (Adam) in a Barab & aacute;si-Albert tree process (T(n) : n >= 1) at large times. More precisely, given epsilon > 0, one wants to output a subset P (epsilon)(n) of vertices of T(n) so that the initial vertex belongs to P (epsilon)(n) with probability at least 1-epsilon when n is large. It has been shown by Bubeck, Devroye and Lugosi, refined later by Banerjee and Huang, that one needs to output at least epsilon(-1+o(1)) and at most epsilon(...

摘要：We explore the relationship between recursive distributional equations and convergence results for finite difference schemes of parabolic partial differential equations (PDEs). We focus on a family of random processes called symmetric cooperative motions, which generalize the symmetric simple random walk and the symmetric hipster random walk introduced in Addario-Berry et al. (Probab Theory Related fields 178(1-2):437-473, 2020). We obtain a distributional convergence result for symmetric coop...

摘要：A variety of physical phenomena involve the nonlinear transfer of energy from weakly damped modes subjected to external forcing to other modes which are more heavily damped. In this work we explore this in (finite-dimensional) stochastic differential equations in Rn\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\...
