Generalized complex geometry and supersymmetric non-linear sigma models
Ulf Lindstrom
After an elementary presentation of the relation between supersymmetric nonlinear sigma models and geometry, I focus on 2D and the target space geometry allowed when there is an ex…
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…
Supersymmetry, a Biased Review
U. Lindström
This set of lectures contain a brief review of some basic supersymmetry and its representations, with emphasis on superspace and superfields. Starting from the Poincaré group, the…
Higher Order Invariants in Supergravity
Ulf Lindstrom
On a historical note, we first describe the early superspace construction of counterterms in supergravity and then move on to a brief discussion of selected areas in string theory…
The topology of multi-coupling deformations of CFT
Ulf Lindstrom, Maxim Zabzine
We discuss the topological properties of the manifold of coupling constants for multi-coupling deformations of conformal field theories. We calculate the Euler and Betti numbers an…
Thermodynamics of N=1 supersymmetric QCD
J. Grundberg, T. H. Hansson, U. Lindström
We use the dual description proposed by Seiberg to calculate the pressure in the low temperature confined phase of supersymmetric QCD using perturbation theory to ,…
