Canonical Quantization of the Reissner-Nordstrom Black Hole via Conditional Symmetries

We use the conditional symmetry approach to study the r-evolution of Reissner-Nordstrom black hole both at the classical and quantum level. We Dirac-quantize the Reissner-Nordstrom black hole using the quantum analogues of the classical conditional symmetries, and show that the existence of such symmetries yields solutions to the Wheeler-DeWitt equation which, as a semiclassical analysis shows, exhibit a good correlation with the classical regime. Finally, we use the resulting wave functions to investigate the possibility of removing the classical singularities.
