| contents | In their physical proposal for quantization [20], Gukov-Witten suggested that, given a symplectic manifold $M$ with a complexification $X$, the A-model morphism spaces $\operatorname{Hom}(\mathcal{B}_{\operatorname{cc}}, \mathcal{B}_{\operatorname{cc}})$ and $\operatorname{Hom}(\mathcal{B}, \mathcal{B}_{\operatorname{cc}})$ should recover holomorphic deformation quantization of $X$ and geometric quantization of $M$ respectively, where $\mathcal{B}_{\operatorname{cc}}$ is a canonical coisotropic A-brane on $X$ and $\mathcal{B}$ is a Lagrangian A-brane supported on $M$.
Assuming $M$ is spin and Kähler with a prequantum line bundle $L$, Chan-Leung-Li [10] constructed a subsheaf $\mathcal{O}_{\operatorname{qu}}^{(k)}$ of smooth functions on $M$ with a non-formal star product and a left $\mathcal{O}_{\operatorname{qu}}^{(k)}$-module structure on the sheaf of holomorphic sections of $L^{\otimes k} \otimes \sqrt{K}$.
In this paper, we give a careful treatment of the relation between (holomorphic) deformation quantizations of $M$ and $X$. As a result, Chan-Leung-Li's work [10] provides a mathematical realization of the action of $\operatorname{Hom}(\mathcal{B}_{\operatorname{cc}}, \mathcal{B}_{\operatorname{cc}})$ on $\operatorname{Hom}(\mathcal{B}, \mathcal{B}_{\operatorname{cc}})$. By Fedosov's gluing arguments, we also construct a $\mathcal{O}_{\operatorname{qu}}^{(k)}$-$\overline{\mathcal{O}}_{\operatorname{qu}}^{(k)}$-bimodule structure on the sheaf of smooth sections of $L^{\otimes 2k}$ to realize the actions of $\operatorname{Hom}(\mathcal{B}_{\operatorname{cc}}, \mathcal{B}_{\operatorname{cc}})$ and $\operatorname{Hom}(\overline{\mathcal{B}}_{\operatorname{cc}}, \overline{\mathcal{B}}_{\operatorname{cc}})$ on $\operatorname{Hom}(\overline{\mathcal{B}}_{\operatorname{cc}}, \mathcal{B}_{\operatorname{cc}})$, which is related to the analytic geometric Langlands program. |
