Domain Walls of D=8 Gauged Supergravities and their D=11 Origin
N. Alonso-Alberca, E. Bergshoeff, U. Gran +3
Performing a Scherk-Schwarz dimensional reduction of D=11 supergravity on a three-dimensional group manifold we construct five D=8 gauged maximal supergravities whose gauge groups…
Supergravity Vacua Today
Natxo Alonso-Alberca, Tomas Ortin
We review the definition of (maximally supersymmetric) vacuum in supergravity theories, the currently known vacua in arbitrary dimensions and how the associated supersymmetry algeb…
Gauged/Massive Supergravities in Diverse Dimensions
Natxo Alonso-Alberca, Tomas Ortin
We show how massive/gauged maximal supergravities in 11-n dimensions with SO(n-l,l) gauge groups (and other non-semisimple subgroups of Sl(n,R)) can be systematically obtained by d…
The Near-Horizon Limit of the Extreme Rotating d=5 Black Hole as a Homogenous Spacetime
N. Alonso-Alberca, E. Lozano-Tellechea, T. Ortin
We show that the spacetime of the near-horizon limit of the extreme rotating d=5 black hole, which is maximally supersymmetric in N=2,d=5 supergravity for any value of the rotation…
An Sl(3,R) multiplet of 8-dimensional type II supergravity theories and the gauged supergravity inside
N. Alonso-Alberca, P. Meessen, T. Ortin
The so-called ``massive 11-dimensional supergravity'' theory gives, for one Killing vector, Romans' massive 10-dimensional supergravity in 10 dimensions, for two Killing vectors an…
Curved dilatonic brane-worlds and the cosmological constant problem
Natxo Alonso-Alberca, Bert Janssen, Pedro J. Silva
We construct a model for dilatonic brane worlds with constant curvature on the brane, i.e. a non-zero four-dimensional cosmological constant, given in function of the dilaton coupl…
