G-theory: U-folds as K3 fibrations
José Morales
(Roma 2 and Oxford)
Abstract
We study N=2 flux vacua describing intrinsic non-perturbative systems of 3- and 7-branes. In the spirit of F-theory, the solutions are described in purely geometric terms with the flux data codified on CY geometries given as K3 fibrations over a two-sphere.
