Smooth structures on the field of prequantum Hilbert spaces

Abstract: When there is a family of complex structures on the phase space, parametrized by a set $S$, the prequantum Hilbert spaces produced by geometric quantization, using the half-form correction, also depends on these parameters. This way we obtain a field of Hilbert spaces $p:H^{pr Q}\rightarrow S$. We show that this field can have natural inequivalent smooth Hilbert bundle structures.
