Maurer-Cartan Equations and Black Hole Superpotentials in N =8 Supergravity (2009)
Ferrara, S, Marrani, A, Orazi, E
We retrieve the non-BPS extremal black hole superpotential of N=8, d=4 supergravity by using the Maurer-Cartan equations of the symmetric space E_7(7)/SU(8). This superpotential was recently obtained...
Maurer-Cartan Equations and Black Hole Superpotentials in N =8 Supergravity (2009)
Ferrara, S., Marrani, A., Orazi, E.
We retrieve the non-BPS extremal black hole superpotential of N=8, d=4 supergravity by using the Maurer-Cartan equations of the symmetric space E_7(7)/SU(8). This superpotential was recently obtained...
Ceresole, A., Ferrara, S., Gnecchi, A., Marrani, A.
We examine few simple extremal black hole configurations of N=8, d=4 supergravity. We first elucidate the relation between the BPS Reissner-Nordstrom black hole and the non-BPS Kaluza-Klein dyonic...
R symmetry and the topological twist of N=2 effective supergravities of heterotic strings (1997)
Fre, P, DAuria, R, Ferrara, S, Soriani, P
We discuss R symmetries in locally supersymmetric N = 2 gauge theories coupled to hypermultiplets which can be thought of as effective theories of heterotic superstring models. In this type of...
Ceresole, A, DAuria, R, Ferrara, S, Fre, P, Regge, T, ...
The generalization of the rigid special geometry of the vector multiplet quantum moduli space to the case of supergravity is discussed through the notion of a dynamical Calabi-Yau 3-fold. Duality...
Duality transformations in supersymmetric yang-mills theories coupled to supergravity (1995)
We consider duality transformations in N = 2, d = 4 Yang-Mills theory coupled to N = 2 supergravity. A symplectic and coordinate covariant framework is established, which allows one to discuss...
