A warm-up for solving noncompact sigma models: The Sinh-Gordon model

room Physics Lecture Theatre

Standard methods like the Bethe ansatz will typically fail when the target space of an integrable model is non-compact like, for example, in the case of the nonlinear sigma models associated to AdS-spaces. New methods are needed. We will discuss some of them in the simplest possible example, the Sinh-Gordon model.
