Full spacetime inversion generated by electromagnetic Abelian gauge transformations
Alcides Garat
In a previous manuscript we addressed the possibility of generating a reflection in a region of spacetime inside a null surface under electromagnetic gauge transformations. In this…
New symmetry in higher curvature spacetimes
Alcides Garat
New symmetries have been found in Einstein-Maxwell spacetimes. New symmetries have also been found in imperfect fluid curved spacetimes. We will prove in this paper that we can ext…
Symmetry evolution for the imperfect fluid under perturbations
Alcides Garat
Ever since a new symmetry was found for the imperfect fluid with vorticity the question of the effect of perturbations on the symmetry itself has been raised. This new symmetry aro…
Tetrads in SU(N) Yang-Mills geometrodynamics
Alcides Garat
The discovery of the SU(3) symmetry was fundamental as to establishing an ordering principle in particle physics. We already studied how to couple the SU(3) symmetry to the gravita…
Isomorphism between the local Poincare generalized translations group and the group of spacetime transformations (x LB1)4
Alcides Garat
We will prove that there is a direct relationship between the Poincare subgroup of translations, and the group of tetrad transformations LB1 introduced in a previous manuscript. LB…
Singular gauge transformations in geometrodynamics
Alcides Garat
The new tetrads introduced previously for non-null electromagnetic fields in Einstein- Maxwell spacetimes enable a direct link to the local electromagnetic gauge group of transform…
New symmetry for the imperfect fluid
Alcides Garat
We will address the existence of a new symmetry for an imperfect fluid by introducing local four-velocity gauge-like transformations for the case when there is vorticity. A similar…
