Alternative Quantization of the Schwarzschild black hole interior in the context of Loop Quantum Gravity, Juan Augusto Cabrera Padilla, UNAM, Mexico

The success of Loop Quantum Cosmology models in describing a FLRW universe with k=0, and resolving the classic Big Bang singularity, has motivated the implementation of similar quantization techniques in other spacetimes. Particularly, these techniques have proven successful to resolve the singularity in the interior of a Schwarzschild black hole, when it is modeled as a Kantowski-Sachs spacetime. There are ambiguities involved in the quantization process of the Hamiltonian Constraint, that must be explored to determine whether the singularity resolution is a robust result of the model, or an artifact of the specific quantization. A proposal is presented to explore the consequences of such ambiguities in the interior of a Schwarzschild Black Hole, that could be useful to learn more features about the full theory.
