The orbit of a -transformation cannot lie in a small interval

DoYong Kwon

For , let be the -transformation. We consider an invariant -orbit closure contained in a closed interval with diameter , then define…

A comment on the paper "Continued fractions and orderings on the Markov numbers, Adv. Math. 370 (2020), 107231"

DoYong Kwon

We discuss the validity of the proof of the fixed numerator conjecture on Markov numbers, which is the main result of the paper mentioned in the title.

A devil's staircase from rotations and irrationality measures for Liouville numbers

Doyong Kwon

From Sturmian and Christoffel words we derive a strictly increasing function . This function is continuous at every irrational point, while at rational p…

Deciding whether a quantum state has secret correlations is an NP-complete problem

Jae-Weon Lee, DoYong Kwon, Jaewan Kim

From the NP-hardness of the quantum separability problem and the relation between bipartite entanglement and the secret key correlations, it is shown that the problem deciding whet…

Sturmian words, -shifts, and transcendence

Dong Pyo Chi, DoYong Kwon

Consider the minimal -shift containing the shift space generated by given Sturmian word. In this paper we characterize such and investigate its combinatorial, dynamical and…
