Critical formation of trapped surfaces in the collision of gravitational shock waves
Luis Alvarez-Gaume, Cesar Gomez, Agustin Sabio Vera +2
We study the formation of marginally trapped surfaces in the head-on collision of two shock waves both in anti-de Sitter and Minkowski space-time in various dimensions as a functio…
Critical gravitational collapse: towards a holographic understanding of the Regge region
Luis Alvarez-Gaume, Cesar Gomez, Agustin Sabio Vera +2
We study the possible holographic connection between the Regge limit in QCD and critical gravitational collapse of a perfect fluid in higher dimensions. We begin by analyzing the p…
Twisted invariances of noncommutative gauge theories
Alvaro Duenas-Vidal, Miguel A. Vazquez-Mozo
We study noncommutative deformations of Yang-Mills theories and show that these theories admit a infinite, continuous family of twisted star-gauge invariances. This family interpol…
Scaling Phenomena in Gravity from QCD
Luis Alvarez-Gaume, Cesar Gomez, Miguel A. Vazquez-Mozo
We present holographic arguments to predict properties of strongly coupled gravitational systems in terms of weakly coupled gauge theories. In particular we relate the latest compu…
On nonanticommutative N=2 sigma-models in two dimensions
Luis Alvarez-Gaume, Miguel A. Vazquez-Mozo
We study nonanticommutative deformations of N=2 two-dimensional Euclidean sigma models. We find that these theories are described by simple deformations of Zumino's Lagrangian and…
Comments on Noncommutative Field Theories
L. Alvarez-Gaume, M. A. Vazquez-Mozo
We discuss some aspects of noncommutative quantum field theories obtained from the Seiberg-Witten limit of string theories in the presence of an external B-field. General propertie…
