Consistency relations and conservation of $\zeta$ in holographic inflation

摘要: It is well known that, in single clock inflation, the curvature perturbation $\zeta$ constant time on superhorizon scales. In standard bulk description this follows quite simply from local conservation of energy momentum tensor bulk. On other hand, a holographic description, constancy must be related to properties RG flow boundary theory. Here, we show independence correlators cut-off theory, and so-called consistency relations for vertex functions with soft leg.
