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 unital C^*-algebra A, acsr(A) is the absolute connected stable rank of A, and (\hat{G})_1 i...

The general problem of "control" may be divided into two main categories, often designated open-loop and closed-loop (see Fig. 1). We adopt here the convention of using "controller" to designate a device that formulates a set of commands intended to change the state of ...
