The real monopole Floer–Seiberg–Witten Floer spectrum isomorphism

Let KK be a nonzero determinant link. Write HMR~(K)\widetilde{\operatorname{HMR}}_{\bullet}(K) for its reduced real monopole Floer homology and let SWFR(K)\operatorname{SWF}_R(K) denote the real Seiberg–Witten Floer spectrum. Then the real monopole Floer–Seiberg–Witten Floer spectrum conjecture. There is an isomorphism

HMR~(K)H~(SWFR(K);F2).\widetilde{\operatorname{HMR}}_{\bullet}(K) \cong \widetilde{H}_*(\operatorname{SWF}_R(K);\mathbb{F}_2).

The conjecture proposes that the algebraically defined real monopole Floer homology agrees with the reduced F2\mathbb{F}_2-homology of the real Seiberg–Witten Floer spectrum. This would relate the mapping-cone construction to the spectrum-level invariant; the source does not state whether the isomorphism is known in general.
