On the stable rank of algebras of operator fields over metric spaces
Ping Wong Ng, Takahiro Sudo
Let G be a finitely generated, torsion-free, two-step nilpotent group. Let C^*(G) be the universal C^*-algebra of G. We show that acsr(C^*(G)) = acsr(C((\hat{G})_1)), where for a u…

On the stable rank of algebras of operator fields over N-cubes
Ping Wong Ng, Takahiro Sudo
Let A be a unital maximal full algebra of operator fields with base space the k-cube [0,1]^k and fibre algebras, say, {A_t}_{t \in [0,1]^k}. Then the stable rank of A is bounded ab…
