Group theoretical construction of two-dimensional supersymmetric models

A general method is proposed to build large classes of two-dimensional supersymmetric models, whose equations of motion can be interpreted as integrability conditions of a set of linear equations. The bosonic limit of these models is studied; further conditions must be imposed to reproduce, in this limit, the known models. In particular the equations of motion and the linear set associated to the Lund-Regge-Pohlmeyer model are supersymmetrized. Through all the work the formalism of differential forms on superspace is used. (orig.)
