A special road to AdS vacua
Davide Cassani, Sergio Ferrara, Alessio Marrani +2
We apply the techniques of special Kaehler geometry to investigate AdS_4 vacua of general N=2 gauged supergravities underlying flux compactifications of type II theories. We formul…
Maurer-Cartan Equations and Black Hole Superpotentials in N =8 Supergravity
S. Ferrara, A. Marrani, E. Orazi
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 wa…
On Quantum Special Kaehler Geometry
S. Bellucci, A. Marrani, R. Roychowdhury
We compute the effective black hole potential V of the most general N=2, d=4 (local) special Kaehler geometry with quantum perturbative corrections, consistent with axion-shift Pec…
SAM Lectures on Extremal Black Holes in d=4 Extended Supergravity
S. Bellucci, S. Ferrara, M. Gunaydin +1
We report on recent results in the study of extremal black hole attractors in N=2, d=4 ungauged Maxwell-Einstein supergravities. For homogeneous symmetric scalar manifolds, the thr…
More on N=8 Attractors
A. Ceresole, S. Ferrara, A. Gnecchi +1
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 Kal…
Duality, Entropy and ADM Mass in Supergravity
Bianca L. Cerchiai, Sergio Ferrara, Alessio Marrani +1
We consider the Bekenstein-Hawking entropy-area formula in four dimensional extended ungauged supergravity and its electric-magnetic duality property. Symmetries of both "large" an…
