Fukaya-category Hochschild–Floer isomorphism conjecture

About 22 years old · traced to

Let XX be a compact symplectic manifold of dimension 2d2d, and let Fuk⁡(X)\operatorname{Fuk}(X) be its Fukaya category. The open-closed Gromov–Witten theory is expected to give a map from the closed TCFT associated to Fuk⁡(X)\operatorname{Fuk}(X) to the Gromov–Witten TCFT of XX, inducing a map

HH∗(Fuk⁡(X))⟶H∗+d(X).HH_\ast(\operatorname{Fuk}(X))\longrightarrow H_{\ast+d}(X).

Fukaya-category Hochschild–Floer isomorphism conjecture. In good circumstances, this map is an isomorphism. This would identify the Hochschild homology of the Fukaya category with the shifted homology of XX; the source states the needed conditions only as “good circumstances.”
