Stabilization of moduli by fluxes

TL;DR

The paper discusses methods to stabilize moduli in string theory compactifications using fluxes, focusing on generalized reductions, gauged supergravity, and flux-deformed geometries with G-structures.

Contribution

It compares two approaches—generalized Scherk-Schwarz reductions with gauged supergravity and flux-deformed geometries via G-structures—for moduli stabilization.

Findings

Fluxes can lift moduli space in string vacua.

G-structures provide a geometric framework for flux compactifications.

Two complementary methods enhance understanding of flux effects.

Abstract

In order to lift the continuous moduli space of string vacua, non-trivial fluxes may be the essential input. In this talk I summarize aspects of two approaches to compactifications in the presence of fluxes: (i) generalized Scherk-Schwarz reductions and gauged supergravity and (ii) the description of flux-deformed geometries in terms of G-structures and intrinsic torsion.
