On the on-shell equivalence of general relativity and Holst theories with nonmetricity, torsion, and boundaries

J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo +1

We study a generalization of the Holst action where we admit nonmetricity and torsion in manifolds with timelike boundaries (both in the metric and tetrad formalism). We prove that…
