Linear and Second-order Geometry Perturbations on Spacetimes with Torsion
Fernando Izaurieta, Eduardo Rodríguez, Omar Valdivia
In order to study gravitational waves in any realistic astrophysical scenario, one must consider geometry perturbations up to second order. Here, we present a general technique for…
The BTZ black hole as a Lorentz-flat geometry
Pedro D. Alvarez, Pablo Pais, Eduardo Rodriguez +2
It is shown that 2+1 dimensional anti-de Sitter spacetimes are Lorentz-flat. This means, in particular, that any simply-connected patch of the BTZ black hole solution can be endowe…
Transgression Forms and Abelian Semigroups in Supergravity
Eduardo Rodríguez
Two main themes populate this Thesis's pages: transgression forms as Lagrangians for gauge theories and the Abelian semigroup expansion of Lie algebras. A transgression form is a f…
The Extended Cartan Homotopy Formula and a Subspace Separation Method for Chern--Simons Theory
Fernando Izaurieta, Eduardo Rodríguez, Patricio Salgado
In the context of Chern--Simons (CS) Theory, a subspace separation method for the Lagrangian is proposed. The method is based on the iterative use of the Extended Cartan Homotopy F…
Euler Chern Simons Gravity from Lovelock Born Infeld Gravity
Fernando Izaurieta, Eduardo Rodriguez, Patricio Salgado
In the context of a gauge theoretical formulation, higher dimensional gravity invariant under the AdS group is dimensionally reduced to Euler-Chern-Simons gravity. The dimensional…
Higher dimensional gravity invariant under the AdS group
Patricio Salgado, Fernando Izaurieta, Eduardo Rodriguez
A higher dimensional gravity invariant both under local Lorentz rotations and under local Anti de Sitter boosts is constructed. It is shown that such a construction is possible bot…
