Generalized Kähler Geometry in (2,1) superspace
Chris Hull, Ulf Lindström, Martin Roček +2
Two-dimensional (2,2) supersymmetric nonlinear sigma models can be described in (2,2), (2,1) or (1,1) superspaces. Each description emphasizes different aspects of generalized Kähl…
New supersymmetric sigma-model duality
Sergei M. Kuzenko, Ulf Lindstrom, Rikard von Unge
We study dualities in off-shell 4D N = 2 supersymmetric sigma-models, using the projective superspace approach. These include (i) duality between the real O(2n) and polar multiplet…
Generalized Kahler manifolds and off-shell supersymmetry
Ulf Lindstrom, Martin Rocek, Rikard von Unge +1
We solve the long standing problem of finding an off-shell supersymmetric formulation for a general N = (2, 2) nonlinear two dimensional sigma model. Geometrically the problem is e…
Poisson-Lie T-plurality
Rikard von Unge
We extend the path-integral formalism for Poisson-Lie T-duality to include the case of Drinfeld doubles which can be decomposed into bi-algebras in more than one way. We give the c…
Noncommutative Solitons: Moduli Spaces, Quantization, Finite Theta Effects and Stability
L. Hadasz, U. Lindstrom, M. Rocek +1
We find the N-soliton solution at infinite theta, as well as the metric on the moduli space corresponding to spatial displacements of the solitons. We use a perturbative expansion…
E8 Quiver Gauge Theory and Mirror Symmetry
Cecilia Albertsson, Bjorn Brinne, Ulf Lindstrom +1
We show that the Higgs branch of a four-dimensional Yang-Mills theory, with gauge and matter content summarised by an E_8 quiver diagram, is identical to the generalised Coulomb br…
