The topological entropy of iterated piecewise affine maps is uncomputable [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
We show that it is impossible to compute (or even to approximate) the topological entropy of a continuous piecewise affine function in dimension four. The same result holds for saturated linear functions in unbounded dimension.

A Billingsley type theorem for Bowen topological entropy of nonautonomous dynamical systems

open access: yesOpen Mathematics, 2022
This article is devoted to the study of the Bowen topological entropy for nonautonomous dynamical systems, which is an extension of the classical definition of Bowen topological entropy. We show that the Bowen topological entropy can be determined by the

Entanglement Entropy in the Ising Model with Topological Defects. [PDF]

open access: yesPhysical Review Letters, 2021
Entanglement entropy (EE) contains signatures of many universal properties of conformal field theories (CFTs), especially in the presence of boundaries or defects.

Tree shift topological entropy [PDF]

open access: yesTheoretical Computer Science, 2017
We give a definition of topological entropy for tree shifts, prove that the limit in the definition exists, and show that it dominates the topological entropy of the associated one-dimensional shift of finite type when the labeling of the tree shares the

Topological entropy for impulsive differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
A positive topological entropy is examined for impulsive differential equations via the associated Poincaré translation operators on compact subsets of Euclidean spaces and, in particular, on tori.

Entropy of foliations with leafwise Finsler structure [PDF]

open access: yesOpuscula Mathematica, 2016
We extend the notion of the geometric entropy of foliation to foliated manifolds equipped with leafwise Finsler structure. We study the relation between the geometric entropy and the topological entropy of the holonomy pseudogroup. The case of a foliated

Bowen entropy for actions of amenable groups [PDF]

open access: yes, 2016
Bowen introduced a definition of topological entropy of subset inspired by Hausdorff dimension in 1973 \cite{B}. In this paper we consider the Bowen's entropy for amenable group action dynamical systems and show that under the tempered condition, the ...

Entropy of Iterated Function Systems and Their Relations with Black Holes and Bohr-Like Black Holes Entropies

open access: yesEntropy, 2018
In this paper we consider the metric entropies of the maps of an iterated function system deduced from a black hole which are known the Bekenstein–Hawking entropies and its subleading corrections.

Hausdorff Dimension and Topological Entropies of a Solenoid

open access: yesEntropy, 2020
The purpose of this paper is to elucidate the interrelations between three essentially different concepts: solenoids, topological entropy, and Hausdorff dimension.
