Spacetime symmetries and geometric diffusion
Marc Basquens, Antonio Lasanta, Emanuel Mompó +2
We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold . Our focus is on spacetimes with a non-trivial isometry group…
Euclidean self-dual gravity: Ashtekar variables without gauge fixing
J. Fernando Barbero G., Marc Basquens, Eduardo J. S. Villaseñor
The Gotay-Nester-Hinds method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashteka…
Consistent and non-consistent deformations of gravitational theories
J. Fernando Barbero G., Marc Basquens, Bogar Díaz +1
We study the internally abelianized version of a range of gravitational theories, written in connection tetrad form, and study the possible interaction terms that can be added to t…
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…
