Local problems on trees from the perspectives of distributed algorithms, finitary factors, and descriptive combinatorics

S Brandt, YJ Chang, J Grebík, C Grunau… - arxiv preprint arxiv …, 2021‏ - arxiv.org
We study connections between distributed local algorithms, finitary factors of iid processes,
and descriptive combinatorics in the context of regular trees. We extend the Borel …

Factors of IID on trees

R Lyons - Combinatorics, Probability and Computing, 2017‏ - cambridge.org
Classical ergodic theory for integer-group actions uses entropy as a complete invariant for
isomorphism of IID (independent, identically distributed) processes (aka product measures) …

Poisson splitting by factors

AE Holroyd, R Lyons, T Soo - 2011‏ - projecteuclid.org
Given a homogeneous Poisson process on ℝ d with intensity λ, we prove that it is possible to
partition the points into two sets, as a deterministic function of the process, and in an …

Point processes, cost, and the growth of rank in locally compact groups

M Abért, S Mellick - Israel Journal of Mathematics, 2022‏ - Springer
Let G be a locally compact, second countable, unimodular group that is nondiscrete and
noncompact. We explore the ergodic theory of invariant point processes on G. Our first result …

Invasion percolation on the Poisson-weighted infinite tree

L Addario-Berry, S Griffiths, RJ Kang - 2012‏ - projecteuclid.org
We study invasion percolation on Aldous' Poisson-weighted infinite tree, and derive two
distinct Markovian representations of the resulting process. One of these is the σ→∞ limit of …

Rewriting History in Integrable Stochastic Particle Systems

L Petrov, A Saenz - Communications in Mathematical Physics, 2024‏ - Springer
Many integrable stochastic particle systems in one space dimension (such as TASEP—
Totally Asymmetric Simple Exclusion Process—and its q-deformation, the q-TASEP) remain …

The Palm groupoid of a point process and factor graphs on amenable and Property (T) groups

S Mellick - arxiv preprint arxiv:2101.07238, 2021‏ - arxiv.org
We define a probability measure preserving and r-discrete groupoid that is associated to
every invariant point process on a locally compact and second countable group. This …

Ergodicity of Poisson products and applications

T Meyerovitch - 2013‏ - projecteuclid.org
In this paper we study the Poisson process over a σ-finite measure-space equipped with a
measure preserving transformation or a group of measure preserving transformations. For a …

Indistinguishability of cells for the ideal Poisson Voronoi tessellation

S Mellick - arxiv preprint arxiv:2408.10009, 2024‏ - arxiv.org
In this note, we resolve a question of D'Achille, Curien, Enriquez, Lyons, and\" Unel by
showing that the cells of the ideal Poisson Voronoi tessellation are indistinguishable. This …

Deterministic thinning of finite Poisson processes

O Angel, A Holroyd, T Soo - Proceedings of the American Mathematical …, 2011‏ - ams.org
Let $\Pi $ and $\Gamma $ be homogeneous Poisson point processes on a fixed set of finite
volume. We prove a necessary and sufficient condition on the two intensities for the …
