Banach \(KK\)-theory and the Baum-Connes conjecture. (English) Zbl 1030.19002
Casacuberta, Carles (ed.) et al., 3rd European congress of mathematics (ECM), Barcelona, Spain, July 10-14, 2000. Volume II. Basel: Birkhäuser. Prog. Math. 202, 34-46 (2001).
This paper discusses progress on the Baum-Connes conjecture. The emphasis is on the motivation for and implementation of the ideas of the author [Invent. Math. 149, 1-95 (2002; Zbl 1084.19003)] for using Banach \(KK\)-theory to attack the conjecture. This clearly written, interesting paper includes some comments on the likely reach and limitations of the author’s techniques.
For the entire collection see [Zbl 0972.00032].
