Matter-coupled higher spin gravities in 3d: no- and yes-go results

Abstract Massless higher-spin fields show no preference for any value of the cosmological constant in 3d. All matter-free higher-spin gravities in 3d are equivalent to Chern-Simons theories with an appropriate choice of gauge algebra. For various reasons, including holography, it is important to enr...
