Aiming at nonexperts, the key mechanisms of higher-spin extensions of ordinary gravities in
four dimensions and higher are explained. An overview of various no-go theorems for low …

We address the uniqueness of the minimal couplings between higher-spin fields and gravity.
These couplings are cubic vertices built from gauge non-invariant connections that induce …

A bstract We derive the characters of all unitary irreducible representations of the (d+ 1)-
dimensional de Sitter spacetime isometry algebra\(\mathfrak {so}\left (1,\kern0. 5em d+ …

Using BRST-BV formulation of relativistic dynamics, we study arbitrary spin massive and
massless fields propagating in flat space. Generating functions of gauge invariant off-shell …

We present some generalities of unfolded on-shell dynamics that are useful in analysing the
BMV conjecture for mixed-symmetry fields in constantly curved backgrounds. In particular …

We review some aspects of higher spin symmetry, in (Anti-) de Sitter and flat space–times,
aiming at closing the gap between the constantly curved and flat cases. On (Anti-) de Sitter …

A contribution to the collection of reviews Introductory Lectures on Higher-Spin Theories
edited by S. Fredenhagen, this introductory article is a pedagogical account of higher-spin …

Free Lagrangians are found both for gauge and non-gauge bosonic conformal fields of any
symmetry type and in any space–time dimension. Conformal gauge fields of various types …

Unfolded equations of motion for symmetric massive bosonic fields of any spin in Minkowski
and (A) dS spaces are presented. Manifestly gauge invariant action for a spin s⩾ 2 massive …

In this paper we elaborate on the gauge invariant frame-like Lagrangian description for the
wide class of the so-called infinite (or continuous) spin representations of Poincaré group …
