Inheritance of Isomorphism Conjectures under colimits, by Arthur Bartels, Siegfried Echterhoff, and Wolfgang Lueck
We investigate when Isomorphism Conjectures, such as the ones due to
Baum-Connes, Bost and Farrell-Jones, are stable under colimits of groups over
directed sets (with not necessarily injective structure maps).
We show in particular that both the K-theoretic Farrell-Jones
Conjecture and the Bost Conjecture with coefficients hold for those groups for which
Higson, Lafforgue and Skandalis have disproved the Baum-Connes Conjecture with
coefficients.
