Three roads to the geometric constraint formulation of gravitational theories with boundaries
Fernando Barbero, Marc Basquens, Valle Varo +1
The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most…
Palatini gravity with nonmetricity, torsion, and boundaries in metric and connection variables
Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo +1
We prove the equivalence in the covariant phase space of the metric and connection formulations for Palatini gravity, with nonmetricity and torsion, on a spacetime manifold with bo…
Covariant phase space for gravity with boundaries: metric vs tetrad formulations
J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo +1
We use covariant phase space methods to study the metric and tetrad formulations of General Relativity in a manifold with boundary and compare the results obtained in both approach…
