The Geometry of Sigma-Models with Twisted Supersymmetry
نویسندگان
چکیده
We investigate the relation between supersymmetry and geometry for two dimensional sigma models with target spaces of arbitrary signature, and Lorentzian or Euclidean world-sheets. In particular, we consider twisted forms of the two-dimensional (p, q) supersymmetry algebra. Superspace formulations of the (p, q) heterotic sigma-models with twisted or untwisted supersymmetry are given. For the twisted (2,1) and the pseudo-Kähler sigma models, we give extended superspace formulations.

Supersymmetric WZ-Poisson sigma model and twisted generalized complex geometry
It has been shown recently that extended supersymmetry in twisted firstorder sigma models is related to twisted generalized complex geometry in the target. In the general case there are additional algebraic and differential conditions relating the twisted generalized complex structure and the geometrical data defining the model. We study in the Hamiltonian formalism the case of vanishing metric...
متن کاملT-duality, quotients and generalized Kähler geometry
In this paper we reopen the discussion of gauging the two-dimensional off-shell (2, 2) supersymmetric sigma models written in terms of semichiral superfields. The associated target space geometry of this particular sigma model is generalized Kähler (or bi-hermitean with two noncommuting complex structures). The gauging of the isometries of the sigma model is now done by coupling the semichiral ...
متن کامل2 00 5 Notes on ( twisted ) lattice supersymmetry
We describe a new approach to the problem of putting supersymmetric theories on the lattice. The basic idea is to discretize a twisted formulation of the supersymmetric theory. For certain theories with extended supersymmetry these twisted formulations contain only integer spin fields. The twisting exposes a scalar nilpotent supercharge which generates an exact lattice symmetry. We gives exampl...
متن کاملN = (4, 4) Supersymmetry and T-Duality
A sigma model with four-dimensional target space parametrized by chiral and twisted chiral N =(2, 2) superfields can be extended to N =(4, 4) supersymmetry off-shell, but this is not true for a model of semichiral fields, where the N = (4, 4) supersymmetry can only be realized on-shell. The two models can be related to each other by T-duality. In this paper we perform a duality transformation f...
متن کاملTwisted N = 2 Supersymmetry with Central Charge and Equivariant Cohomology
We present an equivariant extension of the Thom form with respect to a vector field action, in the framework of the Mathai-Quillen formalism. The associated Topological Quantum Field Theories correspond to twisted N = 2 supersymmetric theories with a central charge. We analyze in detail two different cases: topological sigma models and non-abelian monopoles on four-manifolds.
