Tree-shifts of finite type
N Aubrun, MP Béal - Theoretical Computer Science, 2012 - Elsevier
A one-sided (resp. two-sided) shift of finite type of dimension one can be described as the
set of infinite (resp. bi-infinite) sequences of consecutive edges in a finite-state automaton …

Entropy on regular trees
K Petersen, I Salama - arXiv preprint arXiv:1909.05153, 2019 - arxiv.org
We show that the limit in our definition of tree shift topological entropy is actually the infimum,
as is the case for both the topological and measure-theoretic entropies in the classical …

Sofic tree-shifts
N Aubrun, MP Béal - Theory of Computing Systems, 2013 - Springer
We introduce the notion of sofic tree-shifts which corresponds to symbolic dynamical
systems of infinite ranked trees accepted by finite tree automata. We show that, contrary to …

Hausdorff dimensions of topologically transitive Markov hom tree-shifts
JC Ban, GY Lai, YL Wu - arXiv preprint arXiv:2401.05320, 2024 - arxiv.org
This paper features an analog of Sanov's theorem for finite-state Markov chains indexed by
rooted d-trees, obtained via the method of types in the classical analysis of large deviations …

On the stability and shadowing of tree-shifts of finite type
D Bucki - Proceedings of the American Mathematical Society, 2024 - ams.org
We investigate relations between the pseudo-orbit-tracing property, topological stability and
openness for tree-shifts. We prove that a tree-shift is of finite type if and only if it has the …

[HTML][HTML] A language hierarchy and Kitchens-type theorem for self-similar groups
A Penland, Z Šunić - Journal of Algebra, 2019 - Elsevier
We generalize the notion of self-similar groups of infinite tree automorphisms to allow for
groups which are defined on a tree but may not act faithfully on it. The elements of such a …

Undecidable word problem in subshift automorphism groups
This article studies the complexity of the word problem in groups of automorphisms (or
reversible cellular automata) of subshifts. We show in particular that for any computably …

Tree algebra of sofic tree languages∗
N Aubrun, MP Béal - RAIRO-Theoretical Informatics and Applications, 2014 - cambridge.org
We consider the languages of finite trees called tree-shift languages which are factorial
extensible tree languages. These languages are sets of factors of subshifts of infinite trees …
