Talk title: String Compactification with Fluxes
Abstract:
The addition of non-trivial fluxes to string compactifications induces
a potential for the moduli fields of the effective theory as well as a
backreaction on the geometry of the internal space.
The appearance of a potential is important because it may lead to a
fixing of some or all of the moduli, giving us some understanding about
string vacuum selection and supersymmetry breaking.
We present the general features of these compactifications as well as
examples for the type II and heterotic theory.
Particular attention is devoted to the gauged supergravity description
of the effective theory, the group structures used to construct and
classify the geometry of the solution and the form of the potential and
superpotential which gives the moduli fixing.
