Structure of supergravity theories
Antoine Van Proeyen
We give an elementary introduction to the structure of supergravity theories. This leads to a table with an overview of supergravity and supersymmetry theories in dimensions 4 to 1…
Special geometries, from real to quaternionic
Antoine Van Proeyen
Special geometry is most known from 4-dimensional N=2 supergravity, though it contains also quaternionic and real geometries. In this review, we first repeat the connections betwee…
The unifying superalgebra OSp(1|32)
Eric Bergshoeff, Antoine Van Proeyen
We show how OSp(1|32) gives a unifying framework to describe d=10 type II string theories, d=11 M-theory and d=12 F-theory. The theories are related by different identifications of…
Embedding Branes in Flat Two-time Spaces
L. Andrianopoli, M. Derix, G. W. Gibbons +3
We show how non-near horizon, non-dilatonic -brane theories can be obtained from two embedding constraints in a flat higher dimensional space with 2 time directions. In particul…
Special Kaehler geometry
Antoine Van Proeyen
The geometry that is defined by the scalars in couplings of Einstein-Maxwell theories in N=2 supergravity in 4 dimensions is denoted as special Kaehler geometry. There are several…
Conformal Symmetry on World Volumes of Branes
Piet Claus, Renata Kallosh, Antoine Van Proeyen
We show how the anti-de Sitter isometries of a brane solution of supergravity theory produce superconformal invariance of their world-volume action. In this way linear as well as n…
