Query: Quantization of a Black-Hole Gravity: geometrodynamics and the quantum
  phase-space formalism   Quantum gravity is effective in domains where both quantum effects and
gravity are important, such as in the vicinity of space-time singularities.
This paper will investigate the quantization of a black-hole gravity,
particularly the region surrounding the singularity hidden inside the event
horizon. Describing the system with a Hamiltonian formalism, we apply the
covariant integral quantization method to find the Wheeler-DeWitt equation of
the model. We find that the quantized system has a discrete energy spectrum,
and the time coefficient $g_{00}$ provides the dynamics for this model in a
non-trivial way. Different configurations for the phase space of a
Schwarzschild black hole are obtained in a semi-classical analysis.
