Coassembly is a homotopy limit map

Algebraic Topology 2020-07-29 v3 K-Theory and Homology

Abstract

We prove a claim by Williams that the coassembly map is a homotopy limit map. As an application, we show that the homotopy limit map for the coarse version of equivariant AA-theory agrees with the coassembly map for bivariant AA-theory that appears in the statement of the topological Riemann-Roch theorem.
