Alexandrov groupoids and the nuclear dimension of twisted groupoid ${\mathrm{C}}^{\ast }$-algebras

Kristin Courtney, Anna Duwenig, Magdalena C. Georgescu +2

We consider a twist $E$ over an étale groupoid $G$. When $G$ is principal, we prove that the nuclear dimension of the reduced twisted groupoid ${\mathrm{C}}^{\ast }$-algebra is bounded by…
