Generalized Kähler manifolds and off-shell supersymmetry. (English) Zbl 1114.81077

Summary: 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 equivalent to proving the existence of special coordinates; these correspond to particular superfields that allow for a superspace description. We construct and explain the geometric significance of the generalized Kähler potential for any generalized Kähler manifold; this potential is the superspace Lagrangian.
