TL;DR
This paper reviews the construction of gauged supergravities, which are effective theories from string compactifications with fluxes, emphasizing duality covariance and illustrating with examples.
Contribution
It provides a comprehensive, duality covariant framework for constructing gauged supergravities from flux compactifications, including geometric and non-geometric fluxes.
Findings
Unified description of flux components in gauged supergravities
Explicit examples demonstrating duality covariant construction
Clarification of geometric and non-geometric flux roles
Abstract
The low-energy effective theories describing string compactifications in the presence of fluxes are so-called gauged supergravities: deformations of the standard abelian supergravity theories. The deformation parameters can be identified with the various possible (geometric and non-geometric) flux components. In these lecture notes we review the construction of gauged supergravities in a manifestly duality covariant way and illustrate the construction in several examples.
