A Quasigroup Approach for Conservation Laws in Asymptotically Flat Spacetimes
Alfonso Zack Robles, Alexander I. Nesterov, Claudia Moreno
In the framework of the quasigroup approach to conservation laws in general relativity, we show how the infinite-parametric Newman-Unti group of asymptotic symmetries can be reduce…

Hamiltonian analysis of an Effective action coupled to the Palatini action in 4 dimensions
Ricardo Escobedo, Roberto Santos-Silva, Claudia Moreno +1
We carry out the canonical analysis of the coupling of a -dimensional effective action that arises from a dimensional reduction of a -dimensional BF theory to the Palatini ac…

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…
