Assembly maps

Abstract: We introduce and analyze the concept of an assembly map from the original homotopy theoretic point of view. We give also interpretations in terms of surgery theory, controlled topology and index theory. The motivation is that prominent conjectures of Farrell-Jones and Baum-Connes about K-and L-theory of group rings and group C * -algebras predict that certain assembly maps are weak homotopy equivalences.

“…It is formally dual to the assembly map of [WW95a,DL98], which by [HP04,DL98] coincides with the assembly map of the Farrell-Jones conjecture [FJ93]. A comprehensive recent survey on assembly maps is given in [Lüc19]. The coassembly map is also a close analog of the linear approximation map of embedding calculus [Wei99,GW99].…”
