From Rational Homotopy to K-Theory for Continuous Trace Algebras

John R. Klein, Claude L. Schochet, Samuel B. Smith

Let $A$ be a unital $C^{*}$ -algebra. Its unitary group, $U A$ , contains a wealth of topological information about $A$ . However, the homotopy type of $U A$ is out of reach even for $A =…

Equivalence of higher torsion invariants

Bernard Badzioch, Wojciech Dorabiala, John R. Klein +1

We show that the smooth torsion of bundles of manifolds constructed by Dwyer, Weiss, and Williams satisfies the axioms for higher torsion developed by Igusa. As a consequence we ob…
