Local generation of tilings

T Favereau, M Hoyrup - arxiv preprint arxiv:2411.08697, 2024 - arxiv.org
In this article, we investigate the possibility of generating all the configurations of a subshift
in a local way. We propose two definitions of local generation, explore their properties and …

On the Besicovitch-stability of noisy random tilings

G Léo, S Mathieu - Electronic Journal of Probability, 2023 - projecteuclid.org
In this paper, we introduce a framework for studying a subshift of finite type (SFT) with noise,
allowing some amount of forbidden patterns to appear. Using the Besicovitch distance …

Arithmetical hierarchy of the Besicovitch-stability of noisy tilings

L Gayral, M Sablik - Theory of Computing Systems, 2023 - Springer
The purpose of this article is to study the algorithmic complexity of the Besicovitch stability of
noisy subshifts of finite type, a notion studied in a previous article. First, we exhibit an …

Turing degrees of multidimensional SFTs

E Jeandel, P Vanier - Theoretical Computer Science, 2013 - Elsevier
In this paper, we are interested in computability aspects of subshifts and in particular Turing
degrees of two-dimensional subshifts of finite type (SFTs)(ie, tilings). To be more precise, we …

String attractors and bi-infinite words

P Béaur, F Gheeraert, BH de Menibus - arxiv preprint arxiv:2403.13449, 2024 - arxiv.org
String attractors are a combinatorial tool coming from the field of data compression. It is a set
of positions within a word which intersects an occurrence of every factor. While one-sided …

On pointwise periodicity in tilings, cellular automata, and subshifts

T Meyerovitch, V Salo - Groups, Geometry, and Dynamics, 2019 - ems.press
We study implications of expansiveness and pointwise periodicity for certain groups and
semigroups of transformations. Among other things we prove that every pointwise periodic …

Computational aspects of cellular automata on countable sofic shifts

V Salo, I Törmä - … Symposium on Mathematical Foundations of Computer …, 2012 - Springer
We investigate the computational properties of cellular automata on countable (equivalently,
zero entropy) sofic shifts with an emphasis on nilpotency, periodicity, and asymptotic …

Tilings and model theory

A Ballier, E Jeandel - JAC 2008, 2008 - hal.science
In this paper we emphasize the links between model theory and tilings. More precisely, after
giving the definitions of what tilings are, we give a natural way to have an interpretation of …

An order on sets of tilings corresponding to an order on languages

N Aubrun, M Sablik - arxiv preprint arxiv:0902.1602, 2009 - arxiv.org
Traditionally a tiling is defined with a finite number of finite forbidden patterns. We can
generalize this notion considering any set of patterns. Generalized tilings defined in this way …
