Symplectic Deformations of Gauged Maximal Supergravity
Gianguido Dall'Agata, Gianluca Inverso, Alessio Marrani
We identify the space of symplectic deformations of maximal gauged supergravity theories. Coordinates of such space parametrize inequivalent supergravity models with the same gauge…
No Fermionic Wigs for BPS Attractors in 5 Dimensions
Lorenzo G. C. Gentile, Pietro A. Grassi, Alessio Marrani +2
We analyze the fermionic wigging of 1/2-BPS (electric) extremal black hole attractors in N=2, D=5 ungauged Maxwell-Einstein supergravity theories, by exploiting anti-Killing spinor…
Iwasawa nilpotency degree of non compact symmetric cosets in N-extended Supergravity
Sergio Luigi Cacciatori, Bianca Letizia Cerchiai, Sergio Ferrara +1
We analyze the polynomial part of the Iwasawa realization of the coset representative of non compact symmetric Riemannian spaces. We start by studying the role of Kostant's princip…
