Abstract

Locally trivial bundles of C∗ -algebras with fiber D⊗K for a strongly self-absorbing C∗ -algebra D over a finite CW-complex X form a group E1D(X) that is the first group of a cohomology theory E∗D(X) . In this paper, we compute these groups by expressing them in terms of ordinary cohomology and connective K -theory. To compare the C∗ -algebraic version of gl1(KU) with its classical counterpart we also develop a uniqueness result for the unit spectrum of complex periodic topological K -theory.
