Fukaya category conjecture for compatible tangential structures

About 2 years old · traced to

Let (Θ,Φ)(\Theta,\Phi) be a tangential pair, meaning based spaces equipped with maps fitting into a commutative diagram over BO→BUBO \to BU. Let XX admit a Φ\Phi-structure, set A:=Thom⁡(Ω2Φ→BU×Z)A:= \operatorname{Thom}(\Omega^2\Phi \to BU \times \mathbb{Z}), and let RR be the Thom spectrum of the stable vector bundle over ΩF\Omega F, where FF is the homotopy fibre of Θ→Φ\Theta \to \Phi. Compatible tangential Fukaya-category conjecture. There exists a Fukaya category F(X;A,R)\mathcal{F}(X;A,R) whose objects are exact Lagrangians LL equipped with a compatible Θ\Theta-structure: the diagram L→Θ→BOL \to \Theta \to BO over X→Φ→BUX \to \Phi \to BU commutes, with the horizontal composites classifying TLTL and TXTX. The construction would extend Lagrangian Floer theory to tangential pairs, with coefficients controlled by the AA-algebra RR; existence of this Fukaya category is not established in the supplied text.
