Double field theory (DFT) is a proposal to incorporate T-duality, a distinctive symmetry of
string theory, as a symmetry of a field theory defined on a double configuration space. The …

Within the AdS/CFT correspondence, we review the studies of field theories with a large
number of adjoint and fundamental fields, in the Veneziano limit. We concentrate in set‐ups …

We discuss the four-dimensional N= 1 effective approach in the study of warped type II flux
compactifications with SU (3)× SU (3)-structure to AdS 4 or flat Minkowski space-time. The …

In these lectures we review Generalized Complex Geometry and discuss two main
applications to string theory: the description of supersymmetric flux compactifications and the …

The state of the art in D‐brane model building is briefly reviewed, focusing on recent
achievements in the construction of D= 4 𝒩= 1 type II string vacua with semi‐realistic gauge …

We elaborate on the construction of de Sitter solutions from IIA orientifolds of SU (3)‐
structure manifolds that solve the 10‐dimensional equations of motion at tree‐level in the …

We discuss a novel strategy to construct 4D Script N= 0 stable flux vacua of type II string
theory, based on the existence of BPS bounds for probe D-branes in some of these …

We consider string theory compactifications of the form AdS with orientifold six-planes,
where is a six-dimensional compact space that is either a nilmanifold or a coset. For all …

A bstract We discuss E3-brane instantons in N= 1 F-theory compactifications to four
dimensions and clarify the structure of E3-E3 zero modes for general world-volume fluxes …

A bstract We compute the full classical 4d scalar potential of type IIA Calabi-Yau orientifolds
in the presence of fluxes and D6-branes. We show that it can be written as a bilinear form V …
