We extend the path-integral formulation of Poisson-Lie duality given in [3] to N = 1 supersymmetric σ-models. Using an explicit representation of the generators of the Drinfel'd double corresponding to G⊗U (1) dimG we discuss an application to non-abelian duality. The paper also contains the relevant background and some comments on Poisson-Lie duality. * s.e.hjelmeland@fys.uio.no † ul@physto.se

We derive manifestly locally supersymmetric extensions of the Born-Infeld action with p = 2. The construction is based on a first order bosonic action for Dp-branes with a generalized Weyl invariance. * brinne@physto.se † s.e.hjelmeland@fys.uio.no ‡ ul@physto.se and ulfl@boson.uio.no

Starting from certain 3D non-abelian dual systems, we discuss a number of related dual systems in 2D, some of which are obtained by dimensional reduction. The dualities relate massive scalar and vector fields, and may be relevant for string theory in the context of massive type IIA supergravity. Supersymmetric extensions of the models are also presented.Comment: 16 pages, Late
