We obtain the vacuum solutions for M-theory compactified on eight-manifolds with non-
vanishing four-form flux by analyzing the scalar potential appearing in the three-dimensional …

We determine the N= 1 low energy effective action for compactifications of type IIB string
theory on compact Calabi–Yau orientifolds in the presence of background fluxes from a …

The N= 1 effective action for generic type IIA Calabi–Yau orientifolds in the presence of
background fluxes is computed from a Kaluza–Klein reduction. The Kähler potential, the …

A bstract We give evidence that fully supersymmetric Anti-de Sitter vacua of extended
supergravity with a residual gauge group containing an abelian factor cannot be scale …

Using a Kaluza–Klein reduction of the Dirac–Born–Infeld and Chern–Simons action we
compute the four-dimensional N= 1 effective action for the massless modes of a D7-brane …

This graduate-level primer presents a tutorial introduction to and overview of N= 2
supergravity theories-with 8 real supercharges and in 4, 5 and 6 dimensions. First, the …

We consider type II string theory in space-time backgrounds which admit eight
supercharges. Such backgrounds are characterized by the existence of a (generically non …

The four-dimensional N= 1 supergravity theories arising in compactifications of type IIA and
type IIB on generalized orientifold backgrounds with background fluxes are discussed. The …

In this review article we study type IIB superstring compactifications in the presence of space‐
time filling D‐branes while preserving 𝒩= 1 supersymmetry in the effective four‐dimensional …

Using constraints from supersymmetry and string perturbation theory, we determine the
string loop corrections to the hypermultiplet moduli space of type II strings compactified on a …
