Abstract

For a symplectic manifold admitting a metaplectic structure and for a Kuiper map, we construct a complex of differential operators acting on exterior differential forms with values in the dual of the Kostant's symplectic spinor bundle. Defining a Hilbert CC^*-structure on this bundle for a suitable CC^*-algebra, we obtain an elliptic CC^*-complex in the sense of Mishchenko--Fomenko. Its cohomology groups appear to be finitely generated projective Hilbert CC^*-modules. The paper can serve as a guide for handling of differential complexes and PDEs on Hilbert bundles
