Barbero-like variables derived from Holst action
Merced Montesinos, Jorge Romero, Ricardo Escobedo +1
We work on a spacetime manifold foliated by timelike leaves. In this setting, we explore the solution of the second-class constraints arising during the canonical analysis of the H…
The gauge symmetries of first-order general relativity with matter fields
Merced Montesinos, Diego Gonzalez, Mariano Celada
In -dimensional spacetimes (), there exists an internal gauge symmetry of the Palatini action with a cosmological constant that is the natural generalization of the so-call…
Polynomial -type action for general relativity and anti-self-dual gravity
Diego Gonzalez, Mariano Celada, Merced Montesinos
We report a gravitational -type action principle propagating two (complex) degrees of freedom that, besides the gauge connection and the field, only employs an additional L…
Manifestly Lorentz-covariant variables for the phase space of general relativity
Merced Montesinos, Jorge Romero, Mariano Celada
We present a manifestly Lorentz-covariant description of the phase space of general relativity with the Immirzi parameter. This formulation emerges after solving the second-class c…
