[PDF][PDF] What is topological about topological dynamics?

C Good, S Macıas - DYNAMICAL SYSTEMS, 2018 - mat.bham.ac.uk
We consider various notions from the theory of dynamical systems from a topological point of
view. Many of these notions can be sensibly defined either in terms of (finite) open covers or …

Shifts of finite type as fundamental objects in the theory of shadowing

C Good, J Meddaugh - Inventiones mathematicae, 2020 - Springer
Shifts of finite type and the notion of shadowing, or pseudo-orbit tracing, are powerful tools in
the study of dynamical systems. In this paper we prove that there is a deep and fundamental …

Positive expansivity, chain transitivity, rigidity, and specification on general topological spaces

TT Devi, KB Mangang - Bulletin of the Korean Mathematical …, 2022 - koreascience.kr
We discuss the notions of positive expansivity, chain transitivity, uniform rigidity, chain
mixing, weak specification, and pseudo orbital specification in terms of finite open covers for …

Quasi-shadowing property on compact Hausdorff spaces

L Wang, X Wang - Journal of Mathematical Analysis and Applications, 2025 - Elsevier
In this paper, two topological versions of quasi-shadowing property defined in terms of finite
open covers and uniformities are introduced, which coincide on compact Hausdorff spaces …

Does know its right hand from its left?

W Brian - arxiv preprint arxiv:2402.04358, 2024 - arxiv.org
Let $\sigma $ denote the shift automorphism on $\mathcal {P}(\omega)/\mathrm {fin} $,
defined by setting $\sigma ([A])=[A+ 1] $ for all $ A\subseteq\omega $. We show that the …

ERGODIC SHADOWING, ḏ-SHADOWING AND EVENTUAL SHADOWING IN TOPOLOGICAL SPACES

S Akoijam, KB Mangang - Nonlinear Functional Analysis and …, 2022 - nfaa.kyungnam.ac.kr
We define the notions of ergodic shadowing property, ḏ-shadowing property and eventual
shadowing property in terms of the topology of the phase space. Secondly we define these …

[HTML][HTML] The isomorphism class of the shift map

W Brian - Topology and its Applications, 2020 - Elsevier
The shift map, denoted σ, is the self-homeomorphism of Image 1 induced by the successor
function n↦ n+ 1 on ω. We prove that the isomorphism classes of σ and σ− 1 cannot be …

Equicontinuity, shadowing and distality in general topological spaces

H Wang - Czechoslovak Mathematical Journal, 2020 - Springer
We consider the notions of equicontinuity point, sensitivity point and so on from a topological
point of view. Many of these notions can be sensibly defined either in terms of (finite) open …

Universal flows and automorphisms of P(ω)/fin

W Brian - Israel Journal of Mathematics, 2019 - Springer
We prove that for every countable discrete group G, there is a G-flow on ω* that has every G-
flow of weight≤ ℵ 1 as a quotient. It follows that, under the Continuum Hypothesis, there is a …
