Classification of homogeneous functors by classifying spaces of self-equivalences

From papers

Let M\mathcal{M} and AA be as in the preceding conjecture. For a manifold MM, let FkA(O(M);M)/we\mathcal{F}_{kA}(\mathcal{O}(M);\mathcal{M})/we denote the weak-equivalence classes of degree-kk homogeneous functors with value equivalent to AA, and let Fk(M)F_k(M) denote the configuration space of kk distinct points in MM. Assume additionally, when k2k\geq2, that M\mathcal{M} has a zero object.

Classification conjecture. There are bijections

F1A(O(M);M)/we[M,BhautA]\mathcal{F}_{1A}(\mathcal{O}(M);\mathcal{M})/we\cong [M,\emph{Bhaut} A]

when k=1k=1, and

FkA(O(M);M)/we[Fk(M),BhautA]\mathcal{F}_{kA}(\mathcal{O}(M);\mathcal{M})/we\cong [F_k(M),\emph{Bhaut} A]

when k2k\geq2.

This conjecture would classify homogeneous functors by homotopy classes of maps from the manifold, or from its unordered configuration space in higher degree, into the classifying space of self-weak equivalences of AA. It depends on the preceding conjectural identification of A^\widehat{A} with BhautA\emph{Bhaut} A.
