We present a pedagogical overview of flux compactifications in string theory, from the basic
ideas to the most recent developments. We concentrate on closed-string fluxes in type-II …

Due to the failure of thermodynamics for low temperature near-extremal black holes, it has
long been conjectured that a'thermodynamic mass gap'exists between an extremal black …

In this review we present the most general form of the Janis–Newman algorithm. This
extension allows generating configurations which contain all bosonic fields with spin less …

The general form of N= 2 supergravity coupled to an arbitrary number of vector multiplets
and hypermultiplets, with a generic gauging of the scalar manifold isometries is given. This …

It is shown that the effective five-dimensional theory of the strongly coupled heterotic string is
a gauged version of N= 1 five-dimensional supergravity with four-dimensional boundaries …

We study relations between some topics in number theory and supersymmetric black holes.
These relations are based on the``attractor mechanism''of N= 2 supergravity. In IIB string …

We derive the five-dimensional effective action of strongly coupled heterotic string theory for
the complete (1, 1) sector of the theory by performing a reduction, on a Calabi-Yau three …

We give the full Lagrangean and supersymmetry transformation rules for D= 5, N= 2
supergravity interacting with an arbitrary number of vector, tensor and hyper-multiplets, with …

The scalars in vector multiplets of N= 2 supersymmetric theories in four dimensions exhibit
'special Kähler geometry', related to duality symmetries, due to their coupling to the vectors …
