Query: On the precanonical structure of the Schr\"odinger wave functional in
  curved space-time   The functional Schr\"odinger equation in curved space-time is derived from
the manifestly covariant precanonical Schr\"odinger equation. The Schr\"odinger
wave functional is expressed as the trace of the multidimensional product
integral of precanonical wave function restricted to a field configuration. The
functional Schr\"odinger representation of QFT in curved space-time appears as
a singular limiting case of a formulation based on precanonical quantization,
which leads to a hypercomplex generalization of quantum formalism in field
theory.
