Adams-Iwasawa N=8 Black Holes
Sergio Luigi Cacciatori, Bianca Letizia Cerchiai, Alessio Marrani
We study some of the properties of the geometry of the exceptional Lie group E7(7), which describes the U-duality of the N=8, d=4 supergravity. In particular, based on a symplectic…
On the Scalar Manifold of Exceptional Supergravity
Sergio L. Cacciatori, Bianca L. Cerchiai, Alessio Marrani
We construct two parametrizations of the non compact exceptional Lie group G=E7(-25), based on a fibration which has the maximal compact subgroup K=(E6 x U(1))/Z_3 as a fiber. It i…
The E^3/Z3 orbifold, mirror symmetry, and Hodge structures of Calabi-Yau type
Sergio Luigi Cacciatori, Sara Angela Filippini
Starting from the Kähler moduli space of the rigid orbifold Z=E^3/\mathbb{Z}_3 one would expect for the cohomology of the generalized mirror to be a Hodge structure of Calabi-Yau t…
Magic Coset Decompositions
Sergio L. Cacciatori, Bianca Letizia Cerchiai, Alessio Marrani
By exploiting a "mixed" non-symmetric Freudenthal-Rozenfeld-Tits magic square, two types of coset decompositions are analyzed for the non-compact special Kähler symmetric rank-3 co…
