A Geometric Action Principle for Unification of Yang-Mills Fields, Gravity and Matter Fermions
Pedro D. Alvarez, Fernando Izaurieta, Cristian Quinzacara
A single geometric action, constructed as a linear combination of a restricted six-dimensional family of Clifford-generated invariant terms, simultaneously generates the gravitatio…
(Quasi-)normal modes of rotating black holes and new solitons in Einstein-Gauss-Bonnet
Lilianne Tapia, Monserrat Aguayo, Andrés Anabalón +5
In this paper, we analyze the scalar field (quasi-)normal modes of recently derived rotating black holes within the framework of Einstein-Gauss-Bonnet theory at the Chern-Simons po…
Rotating and accelerating AdS black holes in Einstein-Gauss-Bonnet Gravity
Andres Anabalon, Dumitru Astefanesei, Adolfo Cisterna +4
We present new, exact, rotating and accelerating solutions within the framework of five-dimensional Einstein-Gauss-Bonnet theory at the Chern-Simons point. The rotating solutions d…
Four dimensional topological supergravities from transgression field theory
Patrick Concha, Fernando Izaurieta, Evelyn Rodríguez +1
In this work, we propose a four-dimensional gauged Wess-Zumino-Witten model, obtained as a dimensional reduction from a transgression field theory invariant under the $\mathcal{N}=…
Einstein-Chern-Simons equations on the 3-brane world
F. Izaurieta, P. Salgado, R. Salgado
In this article it is studied the 3-brane world in the context of five-dimensional Einstein-Chern-Simons gravity. We started by considering Israel's junction condition for AdS-Cher…
Chern-Simons--Antoniadis-Savvidy forms and standard supergravity
F Izaurieta, P Salgado, S Salgado
In the context of the so called the Chern--Simons--Antoniadis--Savvidy (ChSAS) forms, we use the methods for FDA decomposition in 1-forms to construct a four-dimensional ChSAS supe…
Randall-Sundrum brane universe as a ground state for Chern-Simons gravity
Fabrizio Cordonier-Tello, Fernando Izaurieta, Patricio Mella +1
In stark contrast with the three-dimensional case, higher-dimensional Chern-Simons theories can have non-topological, propagating degrees of freedom. Finding those vacua that allow…
Minimal AdS-Lorentz supergravity in three-dimensions
O. Fierro, F. Izaurieta, P. Salgado +1
The AdS-Lorentz superalgebra is studied and its relationship to semigroup expansion developed. Using this mathematical tool, the invariant tensors and Casimir opera…
Effectively four-dimensional spacetimes emerging from d=5 Einstein-Gauss-Bonnet Gravity
Fernando Izaurieta, Eduardo Rodríguez
Einstein-Gauss-Bonnet gravity in five-dimensional spacetime provides an excellent example of a theory that, while including higher-order curvature corrections to General Relativity…
On eleven-dimensional Supergravity and Chern-Simons theory
Fernando Izaurieta, Eduardo Rodríguez
We probe in some depth into the structure of eleven-dimensional, osp(32|1)-based Chern-Simons supergravity, as put forward by Troncoso and Zanelli (TZ) in 1997. We find that the TZ…
Standard General Relativity from Chern-Simons Gravity
Fernando Izaurieta, Paul Minning, Alfredo Pérez +2
Chern-Simons models for gravity are interesting because they provide with a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largel…
Dual Formulation of the Lie Algebra S-expansion Procedure
Fernando Izaurieta, Alfredo Pérez, Eduardo Rodríguez +1
The expansion of a Lie algebra entails finding a new, bigger algebra G, through a series of well-defined steps, from an original Lie algebra g. One incarnation of the method, the s…
Semigroup Expansion and M-Supergravity in Eleven Dimensions
Fernando Izaurieta
This thesis deals with the construction of an eleven-dimensional gauge theory, off-shell invariant, for the M Algebra. The theory is built using a Transgression Form as a Lagrangia…

Fernando Izaurieta, Eduardo Rodríguez, Patricio Salgado
A new Lagrangian realizing the symmetry of the M Algebra in eleven-dimensional space-time is presented. By means of the novel technique of Abelian Semigroup Expansion, a link betwe…
Expanding Lie (super)algebras through abelian semigroups
Fernando Izaurieta, Eduardo Rodríguez, Patricio Salgado
We propose an outgrowth of the expansion method introduced by de Azcarraga et al. [Nucl. Phys. B 662 (2003) 185]. The basic idea consists in considering the direct product between…
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…

Fernando Izaurieta, Eduardo Rodríguez, Patricio Salgado
A transgression form is proposed as lagrangian for a gauge field theory. The construction is first carried out for an arbitrary Lie Algebra g and then specialized to some particula…
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…
