Hamiltonian actions in Floer theory

Assume the setting of the Lie monoid action conjecture in Floer theory, with the actions Hamiltonian. Let W(TG)\mathcal{W}(T^*G) and W(TH)\mathcal{W}(T^*H) denote the wrapped Fukaya categories of the cotangent bundles, and let φ\varphi_* and ψ\psi_* be the induced functors. Hamiltonian actions in Floer theory. The wrapped Fukaya categories W(TG)\mathcal{W}(T^*G) and W(TH)\mathcal{W}(T^*H) are dd-curved dd-categories; φ\varphi and ψ\psi induce dd-functors

φ ⁣:W(TG)W(TG),ψ ⁣:W(TH)W(TH);\varphi_*\colon\mathcal{W}(T^*G)\to\mathcal{W}(T^*G'),\qquad \psi_*\colon\mathcal{W}(T^*H)\to\mathcal{W}(T^*H');

the whole co-category Fuk(M)\mathcal{F}uk(M), including non-invariant Lagrangian immersions, is a dd-curved (W(TG),W(TH))(\mathcal{W}(T^*G),\mathcal{W}(T^*H)) uu-bimodule dd-category; and ΦΛ\Phi_\Lambda upgrades to a (φ,ψ)(\varphi_*,\psi_*)-equivariant functor of uu-bimodule dd-categories. The statement extends the preceding Floer conjecture to Hamiltonian actions and non-invariant immersed Lagrangians; the paper presents it as an expected wrapped-Fukaya-theoretic structure.
