Markovian properties of continuous group actions: algebraic actions, entropy and the homoclinic group

S Barbieri, F García-Ramos, H Li - Advances in Mathematics, 2022 - Elsevier
We provide a unifying approach which links results on algebraic actions by Lind and
Schmidt, Chung and Li, and a topological result by Meyerovitch that relates entropy to the …

SFT covers for actions of the first Grigorchuk group

R Grigorchuk, V Salo - arXiv preprint arXiv:2403.06480, 2024 - arxiv.org
We study symbolic dynamical representations of actions of the first Grigorchuk group $ G $,
namely its action on the boundary of the infinite rooted binary tree, its representation in the …

Generalized Gottschalk's conjecture for sofic groups and applications

XK Phung - arXiv preprint arXiv:2403.05998, 2024 - arxiv.org
We establish generalizations of the well-known surjunctivity theorem of Gromov and Weiss
as well as the dual-surjunctivity theorem of Capobianco, Kari and Taati for cellular automata …

Shadowing for families of endomorphisms of generalized group shifts

XK Phung - arXiv preprint arXiv:2011.01524, 2020 - arxiv.org
Let $ G $ be a countable monoid and let $ A $ be an Artinian group (resp. an Artinian
module). Let $\Sigma\subset A^ G $ be a closed subshift which is also a subgroup (resp. a …

On linear non-uniform cellular automata: duality and dynamics

XK Phung - Linear Algebra and its Applications, 2024 - Elsevier
For linear non-uniform cellular automata (NUCA) which are global perturbations of CA over
an arbitrary universe, we introduce and investigate their dual linear NUCA, which are also …

Gromov-Hausdorff distances for dynamical systems

NP Chung - arXiv preprint arXiv:1901.07232, 2019 - arxiv.org
We study equivariant Gromov-Hausdorff distances for general continuous actions which are
not necessarily isometric as Fukaya introduced. We prove that if an action is expansive and …

Strong topological Rokhlin property, shadowing, and symbolic dynamics of countable groups

M Doucha - Journal of the European Mathematical Society, 2024 - ems.press
A countable group G has the strong topological Rokhlin property (STRP) if it admits a
continuous action on the Cantor space with a comeager conjugacy class. We show that …

Expansive actions with specification of sofic groups, strong topological markov property, and surjunctivity

T Ceccherini-Silberstein, M Coornaert, H Li - Journal of Functional Analysis, 2024 - Elsevier
A dynamical system is a pair (X, G), where X is a compact metrizable space and G is a
countable group acting by homeomorphisms of X. An endomorphism of (X, G) is a …

The Lanford–Ruelle theorem for actions of sofic groups

S Barbieri, T Meyerovitch - Transactions of the American Mathematical …, 2023 - ams.org
Let $\Gamma $ be a sofic group, $\Sigma $ be a sofic approximation sequence of $\Gamma
$ and $ X $ be a $\Gamma $-subshift with non-negative sofic topological entropy with …
