A survey on operator $K$ -theory via homotopical algebra

Ulrich Bunke, Markus Land, Ulrich Pennig

This is a survey article with the goal to advertise spectrum valued versions of $K$ - and $K K$ - theory for $C^{*}$ -algebras via a (stable and symmetric monoidal) $\infty$ -categorica…

$K$ -theory of crossed products via homotopy theory

Ulrich Bunke

In this paper we analyse for a $G$ - $C^{*}$ -algebra $A$ to which extent one can calculate the $K$ -theory of the reduced crossed product $K (A ⋊_{r} G)$ from the $K$ -theory spectr…

KK- and E-theory via homotopy theory

Ulrich Bunke

We provide a homotopy theorist's point of view on $K K$ - and $E$ -theory for $C^{*}$ -algebras. We construct stable $\infty$ -categories representing these theories through a sequence…
