Symmetry structure of special geometries
Using techniques from supergravity and dimensional reduction, we study the full isometry algebra of K\"ahler and quaternionic manifolds with special geometry. These two varieties are related by theExpand

New formulations of D = 10 supersymmetry and D8-O8 domain walls
We discuss a generalized form of IIA/IIB supergravity depending on all R-R potentials C-(p) (p = 0, 1,..., 9) as the effective field theory of type IIA/IIB superstring theory. For the IIA case weExpand

Lagrangians of N = 2 supergravity-matter systems
We present explicit expressions for general actions of vector and scalar multiplets coupled to N = 2 supergravity. We outline their construction which is based on the superconformal tensor calculus.Expand

Superconformal Tensor Calculus and Matter Couplings in Six-dimensions
Abstract Using superconformal tensor calculus we construct general interactions of N = 2, d = 6 supergravity with a tensor multiplet and a number of scalar, vector and linear multiplets. We startExpand

Yang-Mills theories with local supersymmetry: Lagrangian, transformation laws and super-Higgs effect
We derive the lagrangian and transformation laws of the coupled Yang-Mills-matter-supergravity system for unextended n = 1 local supersymmetry. We study the super-Higgs effect and the normal HiggsExpand

D-term strings
We study the embedding of cosmic strings, related to the Abrikosov-Nielsen-Olesen vortex solution, into d = 4, N = 1 supergravity. We find that the local cosmic string solution which saturates theExpand

N = 2 supergravity in five dimensions revisited
We construct matter-coupled N = 2 supergravity in five dimensions, using the superconformal approach. For the matter sector we take an arbitrary number of vector, tensor and hypermultiplets. ByExpand

Potentials and symmetries of general gauged N = 2 supergravity-Yang-Mills models
The general couplings of vector multiplets to N = 2 supergravity are presented. The possibility of generalized duality invariance of the bosonic field equations is investigated. Various ways to gaugeExpand

Superconformal algebras in two dimensions with N=4
Abstract We discuss a one-parameter family of d =2 superconformal algebras. They have N =4 supersymmetries and satisfy all the usual requirements. There is one Virasoro algebra, the other generatorsExpand

Fayet-Iliopoulos terms in supergravity without gauged R-symmetry
A bstractWe construct a supergravity-Maxwell theory with a novel embedding of the Fayet-Iliopoulos D-term, leading to spontaneous supersymmetry breaking. The gauging of the R-symmetry is not requiredExpand
