Query: Precanonical Perspective in Quantum Gravity   Quantization of general relativity in metric variables using ``precanonical''
quantization based on the De Donder-Weyl covariant Hamiltonian formulation is
outlined. Elements of classical geometry needed to formulate the (Dirac-like)
wave equation emerge from a self-consistency with the underlying quantum
dynamics of the metric. In this sense the formulation can be viewed as
independent from an arbitrarily fixed background.
