On half-synchronized systems

Somayyeh Jangjooye Shaldehi

A subclass of coded systems containing synchronized systems is the family of half-synchronized systems. In this note, we will consider them and show that the property half-synchron…

On semi-open codes and bi-continuing almost everywhere codes

Dawoud Ahmadi Dastjerdi, Somayyeh Jangjooye Shaldehi

We will show that a system is synchronized if and only if it has a cover whose cover map is semi-open. Also, any factor code on an irreducible sofic shift is semi-open and the imag…

On synchronized non-sofic subshifts

D. Ahmadi Dastjerdi, S. Jangjooye Shaldehi

We show that a synchronized coded system $X$ is intrinsically ergodic of full support if and only if $h (Y)$ , the topological entropy of $Y$ , is less than $h (X)$ whenever $Y$ is a…

Intertwined Synchronized Systems

D. Ahmadi Dastjerdi, S. Jangjooye Shaldehi

An asymmetric-RLL $(d_{1}, k_{1}, d_{0}, k_{0})$ system is a subshift of ${0, 1}^{Z}$ with run of $1$ and $0$ restricted to $S = [d_{1}, k_{1}] \subseteq N_{0} = N \cup {0}$ a…

Equivalencies between beta-shifts and S-gap shifts

D. Ahmadi Dastjerdi, S. Jangjooye Shaldehi

Let $X_{β}$ be a sofic $β$ -shift for $β \in (1, 2]$ . We show that there is an $S$ -gap shift $X (S)$ such that $X_{β}$ and $X (S)$ are right-resolving almost conjugate. Convers…
