IIB seven-branes revisited (2007)
Ortín, T., Hartong, J., Bergshoeff, E., Roest, D.
We re-investigate the construction of half-supersymmetric seven-brane solutions of IIB supergavity. In contrast to previous approaches we allow the occurrence of objects with monodromy Tr Λ ≠ 2....
The supersymmetric configurations of N=2, d=4 supergravity coupled to vector supermultiplets (2006)
We classify all the supersymmetric configurations of ungauged N=2,d=4 supergravity coupled to n vector multiplets and determine under which conditions they are also classical solutions of the...
The supersymmetric configurations of N=2, d=4 supergravity coupled to vector supermultiplets (2006)
We classify all the supersymmetric configurations of ungauged N=2,d=4 supergravity coupled to n vector multiplets and determine under which conditions they are also classical solutions of the...
The Bianchi classification of maximal D = 8 gauged supergravities (2004)
Ortín, T., Nielsen, M., Linares, R., Gran, U., Bergshoeff, E., Roest, D.
We construct maximal D = 8 gauged supergravities by the reduction of D = 11 supergravity over three-dimensional group manifolds. Such manifolds have been classified by Bianchi. We divide the...
The Bianchi Classification of Maximal D=8 Gauged Supergravities (2003)
Bergshoeff, E A, Gran, U G, Linares, R, Nielsen, M, Ortín, T, Roest, D
We perform the generalised dimensional reduction of D=11 supergravity over three-dimensional group manifolds as classified by Bianchi. Thus, we construct eleven different maximal D=8 gauged...
κ-symmetry, supersymmetry and intersecting branes (1997)
Ortín, T., Kallosh, R., Bergshoeff, E., Papadopoulos, G.
We present a new form of κ-symmetry transformations for D-branes in which the dependence on the Born-Infeld field strength is expressed as a relative rotation on the left- and right-moving fields...
Duality Versus Supersymmetry and Compactification (1994)
Bergshoeff, E., Kallosh, R., Ortín, T.
We study the interplay between T-duality, compactification and supersymmetry. We prove that when the original configuration has unbroken space-time supersymmetries, the dual configuration also does...
Supersymmetric string waves (1993)
Kallosh, R., Bergshoeff, E.A., Ortín, T.
We present plane-wave-type solutions of the lowest-order superstring effective action which have unbroken space-time supersymmetries. They are given by a stringy generalization of the Brinkmann...
