Topological pseudo entropy [PDF]

open access: yesJournal of High Energy Physics, 2021
We introduce a pseudo entropy extension of topological entanglement entropy called topological pseudo entropy. Various examples of the topological pseudo entropies are examined in three-dimensional Chern-Simons gauge theory with Wilson loop insertions ...

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, will approximate the entropy of the subshift within the error bound.

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 $X$.

Aspects of Topological String Theory [PDF]

open access: yes, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

The volume entropy of a surface decreases along the Ricci flow [PDF]

open access: yes, 2004
The volume entropy, h(g), of a compact Riemannian manifold (M,g) measures the growth rate of the volume of a ball of radius R in its universal cover.

Scale function vs Topological entropy [PDF]

open access: yes, 2013
In the realm of topological automorphisms of totally disconnected locally compact groups, the scale function introduced by Willis is compared with the topological entropy.

The minimal entropy problem for 3-manifolds with zero simplicial volume [PDF]

open access: yes, 2003
In this note, we consider the minimal entropy problem, namely the question of whether there exists a smooth metric of minimal (topological) entropy, for certain classes of closed 3 ...

Entropy increase in switching systems

open access: yes, 2013
The relation between the complexity of a time-switched dynamics and the complexity of its control sequence depends critically on the concept of a non-autonomous pullback attractor.
