-adic characterization of minimal dendric shifts
F Gheeraert, J Leroy - arxiv preprint arxiv:2206.00333, 2022 - arxiv.org
Dendric shifts are defined by combinatorial restrictions of the extensions of the words in their
languages. This family generalizes well-known families of shifts such as Sturmian shifts …

Balancedness and coboundaries in symbolic systems
V Berthé, PC Bernales - Theoretical Computer Science, 2019 - Elsevier
This paper studies balancedness for infinite words and subshifts, both for letters and factors.
Balancedness is a measure of disorder that amounts to strong convergence properties for …

How to prove that a sequence is not automatic
JP Allouche, J Shallit, R Yassawi - Expositiones Mathematicae, 2022 - Elsevier
Automatic sequences have many properties that other sequences (in particular, non-
uniformly morphic sequences) do not necessarily share. In this paper we survey a number of …

On substitutions preserving their return sets
V Berthé, H Goulet-Ouellet - International Conference on Combinatorics …, 2023 - Springer
We consider the question of whether or not a given primitive substitution preserves its sets of
return words—or return sets for short. More precisely, we study the property asking that the …

Substitutions and Cantor real numeration systems
E Charlier, C Cisternino, Z Masáková… - arxiv preprint arxiv …, 2023 - arxiv.org
We consider Cantor real numeration system as a frame in which every non-negative real
number has a positional representation. The system is defined using a bi-infinite sequence …

String attractors and bi-infinite words
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 partial rigidity of -adic subshifts
We develop combinatorial tools to study partial rigidity within the class of minimal $\mathcal
{S} $-adic subshifts. By leveraging the combinatorial data of well-chosen Kakutani-Rokhlin …
