Integrability of the N=2 boundary sine-Gordon model
arXiv:hep-th/0510099 · doi:10.1088/0305-4470/39/10/009
Abstract
We construct a boundary Lagrangian for the N=2 supersymmetric sine-Gordon model which preserves (B-type) supersymmetry and integrability to all orders in the bulk coupling constant g. The supersymmetry constraint is expressed in terms of matrix factorisations.
