Comments on Dualities on Group Manifolds and Supersymmetry
Svend E. Hjelmeland, Ulf Lindstrom
We review some facts about various T-dualities and sigma models on group manifolds, with particular emphasis on supersymmetry. We point out some of the problems in reconciling Pois…
N=1 supersymmetric path-integral Poisson-Lie duality
Svend E. Hjelmeland, Ulf Lindström
We extend the path-integral formulation of Poisson-Lie duality found by Tyurin and von Unge to N=1 supersymmetric sigma-models. Using an explicit representation of the generators o…
World-Volume Locally Supersymmetric Born-Infeld Actions
Björn Brinne, Svend E. Hjelmeland, Ulf Lindström
We derive manifestly locally supersymmetric extensions of the Born-Infeld action with . The construction is based on a first order bosonic action for -branes with a genera…
Some New Non-Abelian 2D Dualities
H. Gustafsson, S. E. Hjelmeland, U. Lindstrom
Starting from certain 3D non-abelian dual systems, we discuss a number of related dual systems in 2D, some of which are obtained by dimensional reduction. The dualities relate mass…
Duality for the Non-Specialist
S. E. Hjelmeland, U. Lindström
This is the written version of a series of lectures reviewing the basics of duality as applied to p-forms and sigma-models. The ideas are introduced by way of worked examples, ofte…
A stringy black string and a stringy black hole in four dimensions
Bjørn Jensen, Svend E. Hjelmeland
We uplift the static three dimensional black hole solution found by Banados, Teitelboim and Zanelli (BTZ) into four dimensional space time. In this way we obtain a black string sol…
