Spectral dimensionality of spacetime around a radiating Schwarzschild black-hole
Mauricio Bellini, Juan Ignacio Musmarra, Pablo Alejandro Sanchez +1
In this work we study the spectral dimensionality of spacetime around a radiating Schwarzschild black hole using a recently introduced formalism of quantum gravity, where the alter…

Conformal metric perturbations and boundary term as physical source
Juan Ignacio Musmarra, Claudia Moreno, Rafael Hernández-Jiménez
In the context of the Relativistic Quantum Geometry formalism, where the cosmological constant is promoted to a dynamical variable by attributing it a geometric interpretation as a…
