Localization $C^*$-algebras and $K\mkern-2mu$-theoretic duality

Marius Dadarlat, Rufus Willett and Jianchao Wu
Vol. 3 (2018), No. 4, 615–630
DOI: 10.2140/akt.2018.3.615
Abstract

Based on the localization algebras of Yu, and their subsequent analysis by Qiao and Roe, we give a new picture of KK-theory in terms of time-parametrized families of (locally) compact operators that asymptotically commute with appropriate representations.

Keywords
K-theory, duality, operator algebras
