Phase transition for the vacant set of random walk and random interlacements

H Duminil-Copin, S Goswami, PF Rodriguez… - arXiv preprint arXiv …, 2023 - arxiv.org
We consider the set of points visited by the random walk on the discrete torus $(\mathbb

Soft local times and decoupling of random interlacements

S Popov, A Teixeira - Journal of the European Mathematical Society, 2015 - ems.press
In this paper we establish a decoupling feature of the random interlacement process Iu⊂ Zd
at level u, d≥ 3. Roughly speaking, we show that observations of Iu restricted to two disjoint …

Decoupling inequalities and interlacement percolation on G×ℤ

AS Sznitman - Inventiones mathematicae, 2012 - Springer
We study the percolative properties of random interlacements on G× ℤ, where G is a
weighted graph satisfying certain sub-Gaussian estimates attached to the parameters α> 1 …

On the fragmentation of a torus by random walk

A Teixeira, D Windisch - Communications on pure and applied …, 2011 - Wiley Online Library
We consider a simple random walk on a discrete torus\input amssym (\BbbZ/N\BbbZ)^d with

[PDF][PDF] Stochastic processes on random graphs

R van der Hofstad - Lecture notes for the 47th Summer School in …, 2017 - rhofstad.win.tue.nl
In this book, we discuss stochastic processes on random graphs. The understanding of such
processes is interesting from an applied perspective, since random graphs serve as models …

Anatomy of a Gaussian giant: supercritical level-sets of the free field on regular graphs

G Conchon-Kerjan - Electronic Journal of Probability, 2023 - projecteuclid.org
We study the level-set of the zero-average Gaussian Free Field on a uniform random d-
regular graph above an arbitrary level h∈(−∞, h⋆), where h⋆ is the level-set percolation …

On scaling limits and Brownian interlacements

AS Sznitman - Bulletin of the Brazilian Mathematical Society, New …, 2013 - Springer
We consider continuous time interlacements on ℂ d, d≥ 3, and investigate the scaling limit
of their occupation times. In a suitable regime, referred to as the constant intensity regime …

Geometry of the vacant set left by random walk on random graphs, Wright's constants, and critical random graphs with prescribed degrees

S Bhamidi, S Sen - Random Structures & Algorithms, 2020 - Wiley Online Library
We provide an explicit algorithm for sampling a uniform simple connected random graph
with a given degree sequence. By products of this central result include:(1) continuum …
