The return of the four- and five-dimensional preons

José Figueroa-O'Farrill, Jan Gutowski, Wafic Sabra

We prove the existence of 3/4-BPS preons in four- and five-dimensional gauged supergravities by explicitly constructing them as smooth quotients of the AdS_4 and AdS_5 maximally su…

Supergravity vacua and lorentzian Lie groups

Ali Chamseddine, José Figueroa-O'Farrill, Wafic Sabra

We classify maximally supersymmetric backgrounds (vacua) of chiral (1,0) and (2,0) supergravities in six dimensions and, by reduction, also those of the minimal N=2 supergravity in…

Symplectic Embeddings, the Prepotentials and Automorphic Functions of $\frac{S U ( 1 , n )}{U ( 1 ) \otimes S U ( n )}$

W. A. Sabra, S. Thomas, N. Vanegas

The holomorphic homogeneous prepotential encoding the special geometry of the special Kähler manifolds $\frac{S U ( 1 , n )}{U ( 1 ) \otimes S U ( n )}$ is constructed using…
