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…

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…
