On the topological stable rank of certain transformation group \(C^*\)- algebras. (English) Zbl 0667.46045

We consider the crossed product or transformation group \(C^*\)-algebras arising from actions of the group of integers on a totally disconnected compact metrizable space. Under a mild hypothesis, we give a necessary and sufficient dynamical condition for the invertibles in such a \(C^*\)- algebra to be dense. We also examine the property of residual finiteness for such \(C^*\)-algebras.
