Semichiral Sigma Models with 4D Hyperkaehler Geometry
Malin Göteman, Ulf Lindström, Martin Rocek
Semichiral sigma models with a four-dimensional target space do not support extended N=(4,4) supersymmetries off-shell arXiv:0903.2376, arXiv:0912.4724. We contribute towards the u…
Three-dimensional (p,q) AdS superspaces and matter couplings
Sergei M. Kuzenko, Ulf Lindstrom, Gabriele Tartaglino-Mazzucchelli
We introduce N-extended (p,q) AdS superspaces in three space-time dimensions, with p+q=N and p>=q, and analyse their geometry. We show that all (p,q) AdS superspaces with X^{IJKL}=…
Extended supersymmetric sigma models in AdS_4 from projective superspace
Daniel Butter, Sergei M. Kuzenko, Ulf Lindstrom +1
There exist two superspace approaches to describe N=2 supersymmetric nonlinear sigma models in four-dimensional anti-de Sitter (AdS_4) space: (i) in terms of N=1 AdS chiral superfi…
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…
