We present a pedagogical discussion of the emergence of gauged supergravities from M‐theory. First, a review of maximal supergravity and its global symmetries and supersymmetric solutions is given. Next, different procedures of dimensional reduction are explained: reductions over a torus, a group manifold and a coset manifold and reductions with a twist. Emphasis is placed on the consistency of the truncations, the resulting gaugings and the possibility to generate field equations without an… 

Gauged supergravities in various spacetime dimensions

In this review article we study the gaugings of extended supergravity theories in various space‐time dimensions. These theories describe the low‐energy limit of non‐trivial string compactifications.

Gauged supergravities and the physics of extra dimensions

This thesis analyses gauged supergravities in various dimensions and their possible origin from compactifications of string theory. In the effective description the fluxes appear in the theory as

Gaugings and other aspects in supergravity

We discuss various topics in supergravity: gaugings, double field theory and $N=2$ $D=4$ BPS multicenter black holes. We introduce the main features of supergravity, focusing on the aspects of gauged

M-theory Calabi-Yau Quantum Mechanics

This thesis explores an exotic class of M-theory compactifications in which the compact manifold is taken to be a Calabi-Yau five-fold. The resulting effective theory is a one-dimensional N=2

M-theory on Calabi-Yau Five-Folds

We study the compactification of M-theory on Calabi-Yau five-folds and the resulting N = 2 super-mechanics theories. By explicit reduction from 11 dimensions, including both bosonic and fermionic

T-duality invariance, M2-brane bundles and type II classification of gauged supergravities

In this paper we obtain the complete classification of the M2-brane symplectic torus bundles classes with monodromy in $SL(2,\mathbb{Z})$ and their precise T-duality relations among them. There are

On the E10/Massive Type IIA Supergravity Correspondence

In this paper we investigate in detail the correspondence between E10 and Romans' massive deformation of type IIA supergravity. We analyse the dynamics of a non-linear sigma model for a spinning

Critical points of maximal D = 8 gauged supergravities

A bstractWe study the general deformations of maximal eight-dimensional supergravity by using the embedding tensor approach. The scalar potential induced by these gaugings is determined.

Scaling cosmologies of gauged supergravity

We construct exact cosmological scaling solutions in gauged supergravity. We restrict to solutions for which the scalar fields trace out geodesic curves on the scalar manifold. Under these

Duality orbits of non‐geometric fluxes

Compactifications in duality covariant constructions such as generalised geometry and double field theory have proven to be suitable frameworks to reproduce gauged supergravities containing



The domain walls of gauged maximal supergravities and their M-theory origin

We consider gauged maximal supergravities with CSO(p,q,r) gauge groups and their relation to the branes of string and M-theory. The gauge groups are characterised by n mass parameters, where n is the

Symmetric potentials of gauged supergravities in diverse dimensions and Coulomb branch of gauge theories

A class of conformally flat and asymptotically anti--de Sitter geometries involving profiles of scalar fields is studied from the point of view of gauged supergravity. The scalars involved in the

Supergravities with Minkowski x Sphere Vacua

Recently the authors have introduced a new gauged supergravity theory with a positive definite potential in D = 6, obtained through a generalised Kaluza-Klein reduction from D = 7. Of particular

Domain walls in massive supergravities

Gauged D = 9 supergravities and Scherk–Schwarz reduction

Generalized Scherk–Schwarz reductions in which compactification on a circle is accompanied by a twist with an element of a global symmetry G typically lead to gauged supergravities and are classified

Compact and Noncompact Gauged Maximal Supergravities in Three Dimensions

We present the maximally supersymmetric three-dimensional gauged supergravities. Owing to the special properties of three dimensions | especially the on-shell duality between vector and scalar elds,

Supersymmetric solutions of supergravity from wrapped branes

We consider several solutions of supergravity with reduced supersymmetry which are related to wrapped branes, and elaborate on their geometrical and physical interpretation. The Killing spinors are
