U-duality and non-BPS solutions
Gianguido Dall'Agata, Stefano Giusto, Clement Ruef
We derive the explicit action of the U-duality group of the STU model on both BPS and non-BPS extremal multi-center solutions. As the class of known non-BPS extremal solutions is n…
Flow equations and attractors for black holes in N = 2 U(1) gauged supergravity
Gianguido Dall'Agata, Alessandra Gnecchi
We investigate the existence of supersymmetric static dyonic black holes with spherical horizon in the context of N= 2 U(1) gauged supergravity in four dimensions. We analyze the c…
Ultraviolet singularities in classical brane theory
Kurt Lechner
We construct for the first time an energy-momentum tensor for the electromagnetic field of a p-brane in arbitrary dimensions, entailing finite energy-momentum integrals. The constr…
A supersymmetric consistent truncation for conifold solutions
Davide Cassani, Anton F. Faedo
We establish a supersymmetric consistent truncation of type IIB supergravity on the T^{1,1} coset space, based on extending the Papadopoulos-Tseytlin ansatz to the full set of SU(2…
Type IIB supergravity on squashed Sasaki-Einstein manifolds
Davide Cassani, Gianguido Dall'Agata, Anton F. Faedo
We provide a consistent N=4 Kaluza-Klein truncation of type IIB supergravity on general 5-dimensional squashed Sasaki-Einstein manifolds. Our reduction ansatz keeps all and only th…
