Higher-dimensional framed operadic formality conjecture

About 10 years old · traced to

Let MM be a formal, simply connected, oriented closed nn-manifold. Let fen\mathtt{fe}_{n} be the framed little nn-disks operad, let fGH∗(M)\mathtt{f}\mathtt{G}_{H^{*}(M)} be the framed model built from H∗(M)H^{*}(M), and let fen∨\mathtt{f}\mathtt{e}_{n}^{\vee} denote the dual framed operadic structure. Let fFMM\mathtt{f}\mathtt{FM}_{M} and fFMn\mathtt{f}\mathtt{FM}_{n} be the framed Fulton–MacPherson module and operad.

Higher-dimensional framed compatibility conjecture. If the framed little nn-disks operad fen\mathtt{fe}_{n} is formal, then the pair (fGH∗(M),fen∨)(\mathtt{f}\mathtt{G}_{H^{*}(M)},\mathtt{f}\mathtt{e}_{n}^{\vee}) is quasi-isomorphic to the pair (ΩPA∗(fFMM),ΩPA∗(fFMn))(\Omega_{\mathrm{PA}}^{*}(\mathtt{f}\mathtt{FM}_{M}),\Omega_{\mathrm{PA}}^{*}(\mathtt{f}\mathtt{FM}_{n})).

This is a conditional extension of the operadic model to higher dimensions. The source explicitly notes that formality of the framed little nn-disks operad is open in general, and describes the claim as closer to wishful thinking than to a conjecture.
