Nuclear Dimension and Rigidity Results for Virtually Abelian Groups

Frankie Chan, S. Joseph Lippert, Iason Moutzouris +1

Let $G$ be a finitely generated virtually abelian group. We show that the Hirsch length, $h (G)$ , is equal to the nuclear dimension of its group $C^{*}$ -algebra, $dim_{n u c} (C^{*} (G))$ .…

We prove that a Bieberbach group with trivial center is not connective and use this property to show that a Bieberbach group is connective if and only if it is poly-Z.
