Local problems on grids from the perspective of distributed algorithms, finitary factors, and descriptive combinatorics

J Grebík, V Rozhoň - Advances in Mathematics, 2023 - Elsevier
We present an intimate connection among the following fields:(a) distributed local
algorithms: coming from the area of computer science,(b) finitary factors of iid processes …

Distributed algorithms, the Lovász Local Lemma, and descriptive combinatorics

A Bernshteyn - Inventiones mathematicae, 2023 - Springer
In this paper we consider coloring problems on graphs and other combinatorial structures on
standard Borel spaces. Our goal is to obtain sufficient conditions under which such colorings …

Borel Vizing's theorem for graphs of subexponential growth

A Bernshteyn, A Dhawan - Proceedings of the American Mathematical …, 2025 - ams.org
We show that every Borel graph $ G $ of subexponential growth has a Borel proper edge-
coloring with $\Delta (G)+ 1$ colors. We deduce this from a stronger result, namely that an …

Borel versions of the Local Lemma and LOCAL algorithms for graphs of finite asymptotic separation index

A Bernshteyn, F Weilacher - arXiv preprint arXiv:2308.14941, 2023 - arxiv.org
Asymptotic separation index is a parameter that measures how easily a Borel graph can be
approximated by its subgraphs with finite components. In contrast to the more classical …

Large-scale geometry of Borel graphs of polynomial growth

A Bernshteyn, J Yu - arXiv preprint arXiv:2302.04727, 2023 - arxiv.org
We study graphs of polynomial growth from the perspective of asymptotic geometry and
descriptive set theory. The starting point of our investigation is a theorem of Krauthgamer …

Invitation to Local Algorithms

V Rozhoň - arXiv preprint arXiv:2406.19430, 2024 - arxiv.org
This text provides an introduction to the field of distributed local algorithms--an area at the
intersection of theoretical computer science and discrete mathematics. We collect many …

Borel Local Lemma: arbitrary random variables and limited exponential growth

A Bernshteyn, J Yu - arXiv preprint arXiv:2412.11571, 2024 - arxiv.org
The Lov\'asz Local Lemma (the LLL for short) is a powerful tool in probabilistic combinatorics
that is used to verify the existence of combinatorial objects with desirable properties. Recent …

[PDF][PDF] FROM DESCRIPTIVE TO DISTRIBUTED

JAN GREBÍK, Z VIDNYÁNSZKY - vidnyanz.elte.hu
In the past couple of years a rich connection has been found between the fields of
descriptive set theory and distributed computing. Frequently, and less surprisingly, finitary …

Equivariant maps to subshifts whose points have small stabilizers

A Bernshteyn - arXiv preprint arXiv:2106.09673, 2021 - arxiv.org
Let $\Gamma $ be a countably infinite group. Given $ k\in\mathbb {N} $, we use $\mathrm
{Free}(k^\Gamma) $ to denote the free part of the Bernoulli shift action of $\Gamma $ on …
