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… Expand

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… Expand

A bstractWe elaborate on conformal higher-spin gauge theory in three-dimensional (3D) curved space. For any integer n > 2 we introduce a conformal spin-n2$$ \frac{n}{2} $$ gauge field hn=hα1…αn$$… Expand

A bstractWe introduce prepotentials for fermionic higher-spin gauge fields in four space-time dimensions, generalizing earlier work on bosonic fields. To that end, we first develop tools for handling… Expand

A bstractWe consider an interacting theory of an infinite tower of massless higher-spin fields in flat space with cubic vertices and their coupling constants found previously by Metsaev. We compute… Expand
