Abstract
Four-dimensional supergravity theories are reinterpreted in a 12-dimensional F-theory framework, The O(8) symmetry of N = 8 supergravity is related to a reduction of F-theory on T-8, with the seventy scalars formally associated, by O(8) triality, to a fully compactified four-form A(4). For the N = 1 type I model recently obtained from the type IIB string on the Z orbifold, we identify the Kahler manifold of the untwisted scalars in the unoriented closed sector with the generalized Siegel upper-half plane Sp(8,R)/(SU(4) x U(1)). The SU(4) factor reflects the holonomy group of Calabi-Yau four-folds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
