Sigma Models
"... Abstract. We derive and discuss a new type of N = 2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1, 2, 1) multiplets is modified by adding an imaginary antisymmetric tensor to the target space metric, thus completing the latter to a nonsymmetric Her ..."

Topological Massive Sigma Models
, 1995
"... In this paper we construct topological sigma models which include a potential and are related to twisted massive supersymmetric sigma models. Contrary to a previous construction these models have no central charge and do not require the manifold to admit a Killing vector. We use the topological mass ..."

Generalized topological sigma model
"... In this article we will examine a “generalized topological sigma model. ” This socalled “generalized topological sigma model ” is the MTheoretic analog of the standard topological sigma model of string theory. We find that the observables of the theory are elements in the cohomology ring of the mod ..."

Generalized Poisson sigma models.
, 2001
"... A general master action in terms of superfields is given which generates generalized Poisson sigma models by means of a natural ghost number prescription. The simplest representation is the sigma model considered by Cattaneo and Felder. For Dirac brackets considerably more general models are generat ..."

"... We present a unified method of construction of surfaces associated with Grassmannian sigma models, expressed in terms of an orthogonal projector. This description leads to compact formulae for structural equations of twodimensional surfaces immersed in the su(N) algebra. In the special case of the ..."

Gauged heterotic sigma models
, 1994
"... The gauging of isometries in general sigmamodels which include fermionic terms which represent the interaction of strings with background YangMills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and the (1,0) supersymmetri ..."

The Geometry of SigmaModels with Twisted
, 1999
"... We investigate the relation between supersymmetry and geometry for two dimensional sigma models with target spaces of arbitrary signature, and Lorentzian or Euclidean worldsheets. In particular, we consider twisted forms of the twodimensional (p,q) supersymmetry algebra. Superspace formulations of ..."
