3d Conformal Higher Spin Symmetry in 2+1 Dimensional Matter Systems
arXiv:hep-th/0301016
Abstract
The symmetry algebra of massless fields living on the 3-dimensional conformal boundary of AdS(4) is shown to be isomorphic to 3d conformal higher spin algebra (AdS(4) higher spin algebra). A simple realization of this algebra on the free flat 3d massless matter fields is given in terms of an auxiliary Fock module.
