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…
Plebanski-like action for general relativity and anti-self-dual gravity
Mariano Celada, Diego González, Merced Montesinos
We present a new -type action for complex general relativity with or without a cosmological constant resembling Plebanski's action, which depends on an SO(3,) conne…
Barbero's formulation from a -type action with the Immirzi parameter
Mariano Celada, Merced Montesinos, Jorge Romero
Starting from a constrained real -type action for general relativity that includes both the Immirzi parameter and the cosmological constant, we obtain the Ashtekar-Barbero vari…
Lorentz-covariant Hamiltonian analysis of BF gravity with the Immirzi parameter
Mariano Celada, Merced Montesinos
We perform the Lorentz-covariant Hamiltonian analysis of two Lagrangian action principles that describe general relativity as a constrained BF theory and that include the Immirzi p…
