TY - JOUR ID - 59361 AU - Tessarotto, Massimo - Cremaschini, Claudio PY - 2021 TI - The Quantum Regularization of Singular Black-Hole Solutions in Covariant Quantum Gravity JF - Entropy VL - 23 IS - 3 SP - "370-1"-"370-27" EP - "370-1"-"370-27" SN - 10994300 KW - quantum gravity;space-time singular solutions;quantum regularization UR - https://www.mdpi.com/1099-4300/23/3/370 N2 - An excruciating issue that arises in mathematical, theoretical and astro-physics concerns the possibility of regularizing classical singular black hole solutions of general relativity by means of quantum theory. The problem is posed here in the context of a manifestly covariant approach to quantum gravity. Provided a non-vanishing quantum cosmological constant is present, here it is proved how a regular background space-time metric tensor can be obtained starting from a singular one. This is obtained by constructing suitable scale-transformed and conformal solutions for the metric tensor in which the conformal scale form factor is determined uniquely by the quantum Hamilton equations underlying the quantum gravitational field dynamics.
