AdS Chern-Simons Gravity induces Conformal Gravity
Rodrigo Aros, Danilo E. Diaz
The leitmotif of this paper is the question of whether four- and higher even-dimensional Conformal Gravities do have a Chern-Simons pedigree. We show that Weyl gravity can be obtai…
On Wald entropy of black holes: logarithmic corrections and trace anomaly
R Aros, D E Diaz, A Montecinos
Quantum effects due to conformal matter in a black hole background result in universal logarithmic corrections to black-hole entropy. The universality resides in the connection of…
Embedding of two de-Sitter branes in a generalized Randall Sundrum scenario
Rodrigo Aros, Milko Estrada
In this work it is studied a generalization of Randall Sundrum model. It is obtained new behaviors of {\it warp factor}, constraints in that the strong brane has tension of positiv…
Charges and the boundary in Chern Simons gravity
Rodrigo Aros
In this work a new set of boundary conditions for Chern Simons gravity that lead to a fully gauge invariant action is analyzed. This particular form of the action reproduces the st…
Boundary conditions in first order gravity: Hamiltonian and Ensemble
Rodrigo Aros
In this work two different boundary conditions for first order gravity, corresponding to a null and a negative cosmological constant respectively, are studied. Both boundary condit…
The horizon and its charges in the first order gravity
Rodrigo Aros
In this work the algebra of charges of diffeomorphisms at the horizon of generic black holes is analyzed within first order gravity. This algebra reproduces the algebra of diffeomo…
