Hitchin Functionals in N = 2 Supergravity

• Mariana Graña, Jan Louis, Daniel Waldram
• 2005

We consider type II string theory in space-time backgrounds which admit eight supercharges. Such backgrounds are characterized by the existence of a (generically nonintegrable) generalized SU (3)×SU… (More)

Generalized structures of N = 1 vacua

• Mariana Graña, Ruben Minasian, Michela Petrini
• 2005

We characterize N = 1 vacua of type II theories in terms of generalized complex structure on the internal manifold M . The structure group of T (M)⊕T (M) being SU(3)×SU(3) implies the existence of… (More)

× SU ( 3 ) compactification and mirror duals of magnetic fluxes

• Mariana Graña, Jan Louis, Daniel Waldram
• 2006

This paper analyses type II string theories in backgrounds which admit an SU (3)×SU (3) structure. Such backgrounds are designed to linearly realize eight out of the original 32 supercharges and as a… (More)

Supersymmetric Backgrounds from Generalized Calabi-Yau Manifolds

• Mariana Graña, Ruben Minasian, Michela Petrini, Alessandro Tomasiello
• 2004

We show that the supersymmetry transformations for type II string theories on six-manifolds can be written as differential conditions on a pair of pure spinors, the exponentiated Kähler form e and… (More)

The Baryonic Branch of Klebanov-Strassler Solution : a Supersymmetric Family of SU ( 3 ) Structure Backgrounds

• A. Butti, Mariana Graña, Ruben Minasian, Michela Petrini, Alberto Zaffaroni
• 2004

We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that interpolates between Klebanov-Strassler (KS) and Maldacena-Nuñez (MN). The solution is obtained by… (More)

Supersymmetric Three-Form Flux Perturbations on AdS 5

• Mariana Graña
• 2000

We consider warped type IIB supergravity solutions with three-form flux and N = 1 supersymmetry, which arise as the supergravity duals of confining gauge theories. We first work in a perturbation… (More)

Gauge / Gravity Duals with Holomorphic Dilaton

• Mariana Graña, Joseph Polchinski
• 2001

We consider configurations of D7-branes and whole and fractional D3-branes with N = 2 supersymmetry. On the supergravity side these have a warp factor, three-form flux and a nonconstant dilaton. We… (More)

On rack cohomology

• Pavel Etingof, Mariana Graña
• 2003

We prove that the lower bounds for Betti numbers of the rack, quandle and degeneracy cohomol-ogy given in [CJKS] are in fact equalities. We compute as well the Betti numbers of the twisted cohomology… (More)

U-dual fluxes and Generalized Geometry

• G. Aldazabal, Emmanuelle Andrès, Pablo G. Cámara, Mariana Graña
• 2010

We perform a systematic analysis of generic string flux compactifications, making use of Exceptional Generalized Geometry (EGG) as an organizing principle. In particular, we establish the precise map… (More)
