Scale and conformal invariance in 2d σ-models, with an application to $$\mathcal{N}$$ = 4 supersymmetry
Abstract By adapting previously known arguments concerning Ricci flow and the c-theorem, we give a direct proof that in a two-dimensional sigma-model with compact target space, scale invariance implies conformal invariance in perturbation theory. This argument, which applies to a general sigma-model...
