Abstract

Generalizing deformation quantizations with separation of variables of a K\"ahler manifold MM, we adopt Fedosov's gluing argument to construct a category DQ\mathsf{DQ}, enriched over sheaves of C[[]]\mathbb{C}[[\hbar]]-modules on MM, as a quantization of the category of Hermitian holomorphic vector bundles over MM with morphisms being smooth sections of hom-bundles. We then define quantizable morphisms among objects in DQ\mathsf{DQ}, generalizing Chan-Leung-Li's notion [4] of quantizable functions. Upon evaluation of quantizable morphisms at =1k\hbar = \tfrac{\sqrt{-1}}{k}, we obtain an enriched category DQqu,k\mathsf{DQ}_{\operatorname{qu}, k}. We show that, when MM is prequantizable, DQqu,k\mathsf{DQ}_{\operatorname{qu}, k} is equivalent to the category GQ\mathsf{GQ} of holomorphic vector bundles over MM with morphisms being holomorphic differential operators, via a functor obtained from Bargmann-Fock actions.
