Lagrangian formulation of symmetric space sine-Gordon models
The symmetric space sine-Gordon models arise by conformal reduction of ordinary 2-dim \sigma-models, and they are integrable exhibiting a black-hole type metric in target space. We provide a Lagrangian formulation of these systems by considering a triplet of Lie groups F \supset G \supset H. We show...
