Perturbatively exact w 1+∞ asymptotic symmetry of quantum self-dual gravity

Perturbatively exact w 1+∞ asymptotic symmetry of quantum self-dual gravity

Abstract The infinite tower of positive-helicity soft gravitons in any minimally coupled, tree-level, asymptotically flat four-dimensional (4D) gravity was recently shown to generate a w 1+∞ asymptotic symmetry algebra. It is natural to ask whether this classical algebra acquires quantum corrections...
