A topological kagome magnet in high entropy form [PDF]

open access: yesCommunications Physics, 2022
Kagome materials have recently attracted significant attention due to their ability to house both topological and magnetic phases. Here, the authors report a high-entropy Kagome magnet that exhibits an anomalous Hall effect, indicating the nontrivial ...

On the Computability of the Topological Entropy of Subshifts [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We prove that the topological entropy of subshifts having decidable language is uncomputable in the following sense: For no error bound less than 1/4 does there exists a program that, given a decision procedure for the language of a subshift as input,

Entropy as a Topological Operad Derivation

open access: yesEntropy, 2021
We share a small connection between information theory, algebra, and topology—namely, a correspondence between Shannon entropy and derivations of the operad of topological simplices.

Topological entropy

open access: yes, 2017
In this thesis we study topological entropy as an invariant of topological dynamical systems. The first chapter contains basic definitions and examples of topological dynamical systems.

Estimates of topological entropy of continuous maps with applications [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2006
We present a simple theory on topological entropy of the continuous maps defined on a compact metric space, and establish some inequalities of topological entropy. As an application of the results of this paper, we give a new simple proof of chaos in the

On the Categorical Entropy and the Topological Entropy [PDF]

open access: yesInternational Mathematics Research Notices, 2017
To an exact endofunctor of a triangulated category with a split-generator, the notion of entropy is given by Dimitrov-Haiden-Katzarkov-Kontsevich, which is a (possibly negative infinite) real-valued function of a real variable. In this paper, we propose a conjecture which naturally generalizes the theorem by Gromov-Yomdin, and show that the categorical

Topology and topological sequence entropy [PDF]

open access: yesScience China Mathematics, 2019
Let $X$ be a compact metric space and $T:X\longrightarrow X$ be continuous. Let $h^*(T)$ be the supremum of topological sequence entropies of $T$ over all subsequences of $\mathbb Z_+$ and $S(X)$ be the set of the values $h^*(T)$ for all continuous maps $T$ on $X$.
