A note on the nuclear dimension of Cuntz-Pimsner $C^*$-algebras associated with minimal shift spaces (2112.15519v4)
Published 31 Dec 2021 in math.OA and math.DS
Abstract: For every one-sided shift space $X$ over a finite alphabet, left special elements are those points in $X$ having at least two preimages under the shift operation. In this paper, we show that the Cuntz-Pimsner $C*$-algebra $\mathcal{O}_X$ has nuclear dimension 1 when $X$ is minimal and the number of left special elements in $X$ is finite. This is done by describing thoroughly the cover of $X$ which also recovers an exact sequence, discovered before by T. Carlsen and S. Eilers.
