Characterization of all the supersymmetric solutions of gauged N = 1, D = 5 supergravity
We find a complete characterization of all the supersymmetric solutions of nonAbelian gauged N = 1, d = 5 supergravity coupled to vector multiplets and hypermultiplets: the generic forms of theExpand
Manifestly Lorentz-covariant variables for the phase space of general relativity
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 constraints arisingExpand
Barbero's formulation from a $BF$-type action with the Immirzi parameter
Starting from a constrained real $BF$-type action for general relativity that includes both the Immirzi parameter and the cosmological constant, we obtain the Ashtekar-Barbero variables used in theExpand
All the supersymmetric configurations of N = 4, d = 4 supergravity
All the supersymmetric configurations of pure, ungauged, N = 4, d = 4 super-gravity are classified in a formalism that keeps manifest the S and T dualities of the theory. We also find simpleExpand
SU(1,1) Barbero-like variables derived from Holst action
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 Holst action with aExpand
Canonical analysis ofn-dimensional Palatini action without second-class constraints
We carry out the canonical analysis of the $n$-dimensional Palatini action with or without a cosmological constant $(n\geq3)$ introducing neither second-class constraints nor resorting to any gaugeExpand
Canonical analysis of Holst action without second-class constraints
We perform the canonical analysis of the Holst action for general relativity with a cosmological constant without introducing second-class constraints. Our approach consists in identifying theExpand
Hamiltonian analysis of fermions coupled to the Holst action
We report three manifestly Lorentz-invariant Hamiltonian formulations of minimally and nonminimally coupled fermion fields to the Holst action. These formulations are achieved by making a suitableExpand
Revisiting the solution of the second-class constraints of the Holst action
In this paper we revisit the nonmanifestly Lorentz-covariant canonical analysis of the Holst action with a cosmological constant. We take a viewpoint close to that of F. Cianfrani and G. MontaniExpand
Canonical analysis involving first-class constraints only of the $n$-dimensional Palatini action
We carry out the canonical analysis of the n-dimensional Palatini action with or without a cosmological constant (n ≥ 3) introducing neither second-class constraints nor resorting to any gaugeExpand
