Abstract We derive the transverse projection operators for fields with arbitrary integer and half-integer spin on three-dimensional anti-de Sitter space, AdS3. The projectors are constructed in terms of the quadratic Casimir operators of the isometry group SO(2, 2) of AdS3. Their poles are demonstrated to correspond to (partially) massless fields. As an application, we make use of the projectors to recast the conformal and topologically massive higher-spin actions in AdS3 into a manifestly…

We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet inD = 2+1. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor
