Description
It is still an open question how general holographic dualities are, and what they possibly tell us about quantum gravity in asymptotically flat spacetimes. In this talk I will focus on a concrete example of an holographic duality involving higher spin gravity. In particular, I report on recent progress within three-dimensional higher spin gravity concerning the flat space limit and the soft hair proposal therein. I present a new set of boundary conditions for higher spin gravity, inspired by a recent “soft Heisenberg hair"-proposal for General Relativity. The asymptotic symmetry algebra consists of set of affine u(1) current algebras. Its associated canonical charges generate higher spin soft hair. The generators of the three-dimensional higher spin version of the Bondi-Metzner-Sachs algebra arise from composite operators of the affine u(1) currents through a twisted Sugawara-like construction.
