The Meta-Isomorphism Conjecture for functors from spaces to spectra

Let S ⁣:SPACESSPECTRA{\mathbf S} \colon \operatorname{SPACES}\to \operatorname{SPECTRA} be a covariant functor respecting weak equivalences and disjoint unions. For a group GG, let F{\mathcal F} be a family of subgroups and let EF(G)E_{\mathcal F}(G) be the classifying GG-CW-complex for this family. The associated equivariant homology theory is denoted HG(;SB)H_*^G(-;{\mathbf S}^B), with HnG(G/G;SB)πn(S(BG))H_n^G(G/G;{\mathbf S}^B)\cong\pi_n({\mathbf S}(BG)). Meta-Isomorphism Conjecture for S{\mathbf S}. The assembly map induced by the projection pr ⁣:EF(G)G/G\operatorname{pr}\colon E_{\mathcal F}(G)\to G/G is bijective for all nZn\in{\mathbb Z}:

HnG(pr;SB) ⁣:HnG(EF(G);SB)HnG(G/G;SB)πn(S(BG)).H_n^G(\operatorname{pr};{\mathbf S}^B)\colon H_n^G(E_{\mathcal F}(G);{\mathbf S}^B)\to H_n^G(G/G;{\mathbf S}^B)\cong\pi_n({\mathbf S}(BG)).

This is the general assembly-map formulation underlying the later AA-theory Farrell--Jones conjectures; the supplied text gives no resolution status.
