On the Non-renormalization of the AdS Radius
Luca Mazzucato, Brenno Carlini Vallilo
We show that the relation between the 't Hooft coupling and the radius of AdS is not renormalized at one-loop in the sigma model perturbation theory. We prove this by computing the…
Holographic formula for the determinant of the scattering operator in thermal AdS
Danilo E. Díaz
A 'holographic formula' expressing the functional determinant of the scattering operator in an asymptotically locally anti-de Sitter(ALAdS) space has been proposed in terms of a re…
Counting the negative eigenvalues of the thermalon in three dimensions
Rodrigo Aros, Andres Gomberoff, Alejandra Montecinos
Some years ago it was shown that the cosmological constant may be reduced by thermal production of membranes that, after nucleation, collapse into a black hole. The probability of…
BRST Anomaly and Superspace Constraints of the Pure Spinor Heterotic String in a Curved Background
Osvaldo Chandia, Mario Tonin
The pure spinor heterotic string in a generic super Yang-Mills and supergravity background is considered. We determine the one-loop BRST anomaly at the cohomological level. We prov…
Compactification in first order gravity
Rodrigo Aros, Mauricio Romo, Nelson Zamorano
The Kaluza-Klein compactification process is applied in five dimensions to CS gravity, for the anti-de Sitter and Poincaré groups, using the first order formalism. In this context…
Conformal Gravity from AdS/CFT mechanism
Rodrigo Aros, Mauricio Romo, Nelson Zamorano
We explicitly calculate the induced gravity theory at the boundary of an asymptotically Anti-de Sitter five dimensional Einstein gravity. We also display the action that encodes th…
