[图书][B] Progress in high-dimensional percolation and random graphs

M Heydenreich, R Van der Hofstad - 2017 - Springer
This book focuses on percolation on high-dimensional lattices. We give a general
introduction to percolation, stating the main results and defining the central objects. We …

Cutoff for non-negatively curved Markov chains

J Salez - Journal of the European Mathematical Society, 2023 - ems.press
Abstract Discovered by Aldous, Diaconis and Shahshahani in the context of card shuffling,
the cutoff phenomenon has since then been established for a variety of Markov chains …

Cutoff for nonbacktracking random walks on sparse random graphs

A Ben-Hamou, J Salez - 2017 - projecteuclid.org
A finite ergodic Markov chain exhibits cutoff if its distance to stationarity remains close to 1
over a certain number of iterations and then abruptly drops to near 0 on a much shorter time …

Cutoff at the “entropic time” for sparse Markov chains

C Bordenave, P Caputo, J Salez - Probability Theory and Related Fields, 2019 - Springer
We study convergence to equilibrium for a class of Markov chains in random environment.
The chains are sparse in the sense that in every row of the transition matrix P the mass is …

Random walk on sparse random digraphs

C Bordenave, P Caputo, J Salez - Probability Theory and Related Fields, 2018 - Springer
A finite ergodic Markov chain exhibits cutoff if its distance to equilibrium remains close to its
initial value over a certain number of iterations and then abruptly drops to near 0 on a much …

Voter models on subcritical scale‐free random graphs

J Fernley, M Ortgiese - Random Structures & Algorithms, 2023 - Wiley Online Library
The voter model is a classical interacting particle system modelling how consensus is
formed across a network. We analyze the time to consensus for the voter model when the …

Cutoff at the entropic time for random walks on covered expander graphs

C Bordenave, H Lacoin - Journal of the Institute of Mathematics of …, 2022 - cambridge.org
It is a fact simple to establish that the mixing time of the simple random walk on a d-regular
graph with n vertices is asymptotically bounded from below by. Such a bound is obtained by …

Expansion in supercritical random subgraphs of the hypercube and its consequences

J Erde, M Kang, M Krivelevich - The Annals of Probability, 2023 - projecteuclid.org
It is well known that the behaviour of a random subgraph of ad-dimensional hypercube,
where we include each edge independently with probability p, undergoes a phase transition …

Cutoff for almost all random walks on abelian groups

J Hermon, S Olesker-Taylor - arXiv preprint arXiv:2102.02809, 2021 - arxiv.org
Consider the random Cayley graph of a finite group $ G $ with respect to $ k $ generators
chosen uniformly at random, with $1\ll\log k\ll\log| G| $; denote it $ G_k $. A conjecture of …

Universality of cutoff for graphs with an added random matching

J Hermon, A Sly, P Sousi - The Annals of Probability, 2022 - projecteuclid.org
We establish universality of cutoff for simple random walk on a class of random graphs
defined as follows. Given a finite graph G=(V, E) with| V| even we define a random graph …
