Coassembly is a homotopy limit map

Cary Malkiewich and Mona Merling
Vol. 5 (2020), No. 3, 373–394
DOI: 10.2140/akt.2020.5.373
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 A-theory agrees with the coassembly map for bivariant A-theory that appears in the statement of the topological Riemann–Roch theorem.

In memory of Bruce Williams
